Add support for Heltec HRU-3601

Browse Source 
Board is very similar to the Heltec HT-C62 based boards (Heltec HT62 variant) but due to wiring of SK6812 Neopixel LED to GPIO2 it becomes incompatible due to the regular HT-C62 dev board using a simple LED on the same GPIO. Depends on [protobufs#521](https://github.com/meshtastic/protobufs/pull/521).

Works:

* SK6812 Neopixel on GPIO2
* [GXCAS GXHTV3](https://www.lcsc.com/product-detail/Temperature-Sensors_GXCAS-GXHTV3C_C5441730.html) (SHTC3 compatible)

Won't fix:

* Battery reading - Board has no voltage divider on VBAT (board has a 1.25mm pitch "JST" style connector and a TP4054 charge IC)
* Main thread LED - Board has no LED on simple GPIO
