v1.7.2

Registers 0x1900-0x1903 (System SOC Calibration Enable, Set, Cycle Mode,
Cycle Days) return Illegal Data Address (exception_code=2) on current inverter
firmware regardless of whether FC6 or FC16 is used. Removed all 6 entities:
the two write switches, number, select, and their two backing read sensors.

The read-only Battery SOC Calibration status sensor at 0x012F is unaffected.
Use a Home Assistant automation to trigger calibration via the AlphaESS app
or inverter web UI instead.
