Possibility to change tx_payload_buffer_size

[Kacp3r3]

Maximum size of the tx paylod buffer was fixed value, there should be possibility to extend this value by user, so i added a new member variable with according setter function.

This gave me a headache, and I had to change the define manually because Arduino uses old version of this library.

@aentinger maybe it's time to consider merging it, as it seems like a bug and I think we were not the only one who came across this issue. At least it should be mentioned somewhere that if long MQTT messages are cut/truncated then you should check the value of this definition, as this is behavior that is being observed in effect.
Thanks!

I will merge this, if @Kacp3r3 drops 3331408 from this patch.
