Yagusmart iMeter 3PN Energy Monitor. (#5229)

* Yagusmart iMeter 3PN Energy Monitor.

* Roll back wrong translation_key naming.

* fix(imeter_3pn_energymonitor): rename file and device

- follow naming convention of including device type in filename to assist users in finding probable matches for other devices
- exclude branding and follow HA naming convention for device name
