Add support for MS-3000 inverter (#299)

* split register map into multiple maps

* add base support reg mapping 0x01900000

* fix shadowed builtin

* detect reg mapping for sensor automatically

* add device and test regs for MS-3000

* add more register mappings

* fix unit tests

* add more MS-3000 registers

* build modell string for TSUN MS-3000

* add MS3000 unit test

* remove obsolete method __set_config_parms

* fix start addr of modbus scans

- in server mode the start addr must be reduced
  by mb_step

* add tests for sensor_list of ms-3000 inverters

* MS-3000: add integer test register

* DCU-1000: add Out Status register

* add integer test and batterie out register

* fix Sonar Qube finding

* DCU-1000: add temp sensors
