Advice for using it with 8-bit AVR MCU

[jputcu]

Hello, I'm considering using this nice library on our limited 8-bit AVR MCU. I probably will have to tweak it:

• store all strings, especially the format string, in flash (PSTR, PROGMEM)
• provide C++ interface
• handle sending and receiving using MCU interrupts which probably requires a caching the format variables.
• perhaps package it with Conan

Do you have any suggestions, existing attempts, research? Are you accepting pull requests (respecting backwards compatibility)?

Thanks

Joris
