@tommag I think if the target address is invalid, the function should return 0 since nothing was transferred. Maybe we could put everything dealing with port writing, port closing, and reporting numBytesIncl in the first if statement and return 0 otherwise

@tommag I think it would be good to double check that the requested data length matches the struct the sender wants to report. There should be a check for this either at the sketch or lib level. Also, it might be nice to request a specific packet type (Packet ID field)

Hi !
Thanks for your work and sharing the lib !
I added new methods to handle I2C requestFrom functions. This allows to transfer data from I2C slave to I2C master as well as I2C 2-way communication.
Request and reply examples are provided and tested on Raspberry Pi Pico (but should work on all platforms)
Solves issues #81 and #106.
