Advance version number to 1.72.1

Commit 73047cdee6 merged the old
migrateToNativeFormatNames() and migrateBarcodeFormatName() mapping
functions, but the new map was based on the former, which happened to be
missing the entry for DATA_BAR.

Fixes: #636

-## RenderScript
+## Deep Links
 
-This app uses [RenderScript][rs] to resize and rotate the camera image.
-Unfortunately, RenderScript has some nasty gotchas.
+You can invoke Binary Eye with a web URI intent from anything that can
+open URIs.
 
-### RenderScript.forceCompat()
+### Decoding
 
-It's necessary to call `RenderScript.forceCompat()` on some devices/roms.
+1. [binaryeye://scan](binaryeye://scan) (note: GitHub does not render this as clickable link)
+2. [http(s)://markusfisch.de/BinaryEye](http://markusfisch.de/BinaryEye)
 
-`RenderScript.forceCompat()` needs to be run before any other RenderScript
-function and unfortunately there is no way to know if invoking `forceCompat()`
-is necessary or not.
+If you want to get the scanned contents, you can add a `ret` query
+argument with a (URL encoded) URI template. For example:
 
-If `RenderScript.forceCompat()` is necessary, a `RSRuntimeException` will
-be thrown and the only option is to restart the app, this time with calling
-`forceCompat()` first.
+[http://markusfisch.de/BinaryEye?ret=http%3A%2F%2Fexample.com%2F%3Fresult%3D{RESULT}](http://markusfisch.de/BinaryEye?ret=http%3A%2F%2Fexample.com%2F%3Fresult%3D{RESULT})
 
-Calling `RenderScript.forceCompat()` means the processing is done in
-software so you probably don't want to enable it by default.
+Supported symbols are:
 
-### 2D barcodes
+* `RESULT` - scanned content
+* `RESULT_BYTES` - raw result as a hex string
+* `FORMAT` - barcode format
 
-If you want to fork this and are only interested in reading 2D barcodes
-(like QR or Aztec), you may want to remove the custom rotation kernel
-altogether as ZXing can read 2D barcodes in any orientation.
+### Encoding
 
-This will make your app a bit simpler and saves you from compiling a
-custom RenderScript kernel for each architecture you want to support.
+1. [binaryeye://encode](binaryeye://encode)
+
+You can use the URL arguments `content` and `format` to automatically
+preset this data. For example:
+
+1. [binaryeye://encode?content=Test&format=QR_CODE](binaryeye://encode?content=Test&format=QR_CODE)
+2. [http(s)://markusfisch.de/encode?content=Test&format=QR_CODE](http://markusfisch.de/encode?content=Test&format=QR_CODE)
+3. [http(s)://markusfisch.de/encode?content=Test&format=DATA_MATRIX](http://markusfisch.de/encode?content=Test2&format=DATA_MATRIX&execute)
+
+If you want the code to be generated immediately, add `execute=true` (or
+just `execute`).
+
+## Intents
+
+You can also use Binary Eye from other apps by using an [Intent][intent].
+
+If you prefer to integrate a barcode scanner into your app, take a look at
+[BarcodeScannerView][barcode_scanner_view] (if you also want to use
+[ZXing-C++][zxing_cpp]) or read how to
+[scan barcodes with ML Kit on Android][mlkit_barcode_scanning].
+
+### SCAN Intent
+
+Use the `com.google.zxing.client.android.SCAN` `Intent` with
+[startActivityForResult()][start_activity] like this:
+
+```kotlin
+startActivityForResult(
+	Intent("com.google.zxing.client.android.SCAN"),
+	SOME_NUMBER
+)
+```
+
+And process the result in [onActivityResult()][on_activity_result] of your
+`Activity`:
+
+```kotlin
+override fun onActivityResult(
+	requestCode: Int,
+	resultCode: Int,
+	data: Intent?
+) {
+	when (requestCode) {
+		SOME_NUMBER -> if (resultCode == RESULT_OK) {
+			val result = data.getStringExtra("SCAN_RESULT")
+			…
+		}
+	}
+}
+```
+
+If you're using AndroidX, this would be the new,
+[recommended way][intent_result]:
+
+```kotlin
+class YourActivity : AppCompatActivity() {
+	private val resultLauncher = registerForActivityResult(
+		ActivityResultContracts.StartActivityForResult()
+	) { result ->
+		if (result.resultCode == RESULT_OK) {
+			val content = result.data?.getStringExtra("SCAN_RESULT")
+			…
+		}
+	}
+
+	fun openScanner() {
+		resultLauncher.launch(Intent("com.google.zxing.client.android.SCAN"))
+	}
+}
+```
+
+## Forwarding scans via Bluetooth
+
+**Note:** The companion apps aren't developed nor maintained by the
+author of Binary Eye.
+
+In order to set up Bluetooth forwarding to a computer:
+
+1. Pair your devices (phone and pc) if not paired already
+2. Download and run a companion app:
+	- Windows: https://github.com/KamaleiZestri/BinaryReceptorWindows
+	- Linux: https://github.com/sean666888/bin_eye_bt_receiver
+3. In the settings of Binary Eye, enable "Forward scans with Bluetooth"
+	and select the appropriate target host device that is running the
+	companion application.
