add support for sending sharing intents with type text/x-keystrokes (like andOTP)

[wschlich]

The (now unmaintained) Android app andOTP supportes sending OTPs as keystrokes (sharing intent with type text/x-keystrokes) when tapping on them (single tap and double tap actions are configurable) to apps that support it, for example:

• KDE Connect (sending OTPs via network to a computer (or device) running KDE Connect (under KDE, Windows, Android...)
• ShareToInputStick (sending OTPs via BT to a USB InputStick that acts as a HID keyboard)

Can you please add support for sending OTPs via sharing intent with type text/x-keystrokes to Aegis as well with a configurable tap action option ('copy', 'send as keystrokes')?

Also, allowing to configure a double tap action like andOTP would be nice, so one could choose between 'copy' and 'send as keystrokes' for single and double tap (I can create a separate issue if you think this feature would be useful).

Thank you! 😃
