Sshd4a

An 'sshd' server with shell access, rsync and scp/sftp services.
New in version 1.13.2
FIXES:

- GitHub #34: starting the service on a Pixel device with Android 17 was failing
due to new enforcements by the OS.
- temporary going back to targetting Android 16. The app still works/supports Android 17.
This solves complication seen in #34.
Sshd4a provides an 'sshd' server with shell access, rsync and scp/sftp services.
Services are provided by:
