getHwModelValue

open fun getHwModelValue(): Int

TBEAM, HELTEC, etc...
Starting in 1.2.11 moved to hw_model enum in the NodeInfo object.
Apps will still need the string here for older builds
(so OTA update can find the right image), but if the enum is available it will be used instead.
.meshtastic.HardwareModel hw_model = 5;

Return

The enum numeric value on the wire for hwModel.
