Rewrite the sailtrack-x708_* scripts

[matteocarnelos]

Currently, the sailtrack-x708_* scripts are written in bash. Consider moving to an other language for these scripts. This would make it easier to modify and debug, and it would make them more consistent with the other non-bash scripts.

It seems also that we have some problem with GPIO pin, in particular reading the satuts of sailtrack-x708_pwr.service I've seen this.

Upon further investigation, it seems this problem stems from a malfunction with the Geekworm X708 V2 shield. Despite the error message, the script itself appears to be functioning correctly.
To address this issue and ensure consistency, I'm currently developing a Python script to replace the existing bash script.
