Pim van den Berg 8b34069fc6 feat(convert-itho-db): convert an itho servicetool database to sqlite
The SQLite database (a subset of the Itho database) can be used to
dynamically interact with an Itho WPU based on the WPU version.

> usage: convert-itho-db.py [-h] --itho-db [ITHO_DB] [--sqlite-db [SQLITE_DB]]
>                           [--force]
>
> Convert Itho Servicetool database to SQLite
>
> optional arguments:
>   -h, --help            show this help message and exit
>   --itho-db [ITHO_DB]   Itho Database file (default: None)
>   --sqlite-db [SQLITE_DB]
>                         Itho Database file (default: heatpump.sqlite)
>   --force               Force overwrite SQLite database (default: False)
