Add support for Louvolite R1942-6CH-WH Remote

[art103]

Please find support for a Louvolite 433.920MHz remote blind control.
In order to use this with a CC1101 attached to an ESP32C3 I had to modify the default radio settings and platformio.ini.
As such, this pull request isn't in a state where it can be merged as is, but I wanted to start the conversation on whether there is a desire to have support merged (and address the CC1101 rxbw limitation).

Highlights:

• TX / RX of R1942-6CH-WH remote, including uuid, node and command with CSUM calculation
• Update esp32-c3-devkitm-1 to support serial console (needs additional defines)
• Change rxBandwidth to a legal cc1101 value (See issue cc1101 bandwith setting #103)
• Change rxBitrate in order to support fine enough granularity for this remote

Edit: Async mode must be enabled.
