Is your feature request related to a problem? Please describe.
While using CC1101 modules would maintain compatibility with the various modules supported by OpenEPaperLink, finding ones that specifically support 868/915 MHZ is difficult.
Describe the solution you'd like
I propose (for the AP codebase) replacing the CC1101 implementation with RadioLib, which supports a wider range of modules.
Describe alternatives you've considered
The only alternative is ordering a CC1101 and hoping it's frequency range is not mislabeled, or modding one to support the correct frequency.
Additional context
Just wanted to get the maintainer's thoughts on this. I'd be willing to implement an alternative
SubGigRadio.cthat uses RadioLib. I have a combo ESP32-S3 + SX1262 module that I can test it with.https://www.amazon.com/dp/B0DLVVLSZB

Don't waste your time with the cheap generic modules, get a EByte E07-900M10S. They are available and high quality.
See https://github.com/OpenEPaperLink/OpenEPaperLink/wiki/Yellow-AP-with-EByte-CC1101-module for more info.
Pull requests using radiolib are welcome, but be aware that we use the TI CRC which is not supported by all hardware. Of course it can be implemented in software as well.
