Shutdown splash for the OLED script; restore non-Latin transliteration; other refactoring (#991)
- Bring back the shutdown splash, with the tweak that is blanks out after 700ms
- Restore the non-Latin transliteration originally from https://github.com/akuker/RASCSI/pull/449 which was lost when the `common` package was introduced
- Bump to the latest libraries, while removing implicit dependencies from requirements.txt
- Shorter duration of the startup splash
- Reintroduce shell shutdown/reboot methods for use with the Web UI. This addresses https://github.com/akuker/RASCSI/issues/538 (the ctrlboard client will continue to use the built-in rascsi system calls which are slightly faster)
- Remove overt references to RPi. This addresses https://github.com/akuker/RASCSI/issues/990
- Other refactorings

RaSCSI Common Python Module

The common module contains python modules that are shared among multiple Python applications such as the OLED or the Web application. It contains shared functionality. For example, the rascsi python module provides functionality for accessing rascsi through its protobuf interface and provides convenient classes for that purpose.

Usage

To make use of the rascsi python module, it needs to be found by the Python scripts using it. This can be achieved in multiple ways. One way is to simply adapt the PYTHONPATH environment variable to include the common/src directory:

PYTHON_COMMON_PATH=${path_to_common_directory}/common/src
export PYTHONPATH=$PWD:${PYTHON_COMMON_PATH}
python3 myapp.py

The most interesting functions are likely found in the classes RaCtlCmds and FileCmds. Classes can be instantiated, for example, as follows (assuming that rascsi host, rascsi port and token are somehow retrieved from a command line argument):

sock_cmd = SocketCmds(host=args.rascsi_host, port=args.rascsi_port)
ractl_cmd = RaCtlCmds(sock_cmd=sock_cmd, token=args.token)

Usage examples can be found in the existing RaSCSI Python applications.
