"""The AMS Lite gets its serial number and firmware from get_version (#3348).

Like every AMS, the AMS Lite reports both only in the printer's get_version
answer, as a module of its own: "ams_f1/<id>". That prefix was not recognised,
so the module was skipped and the unit showed neither. The module names and
fields below are from real A1 and A2L captures (ha-bambulab mock data). The
A2L reports its AMS Lite as unit 16, which is stored as 6.
