[Oberon] FPGA - nRF24L01 `RPI Net' server

[Tomas Kral]

Hi,

I have made some progress. I am able to transmit packets of
multiple payloads. The trick seems in adjusting time loop constants in
various places, plus delays and retries. The setting slightly differs
between `PI' and `Oberon', having no exact explanation, except that each
platform runs at different speed. This may brake compatibility
though with other `Oberon' station nodes, as I have only one `FPGA'
board and one `PI' this may not be an issue.

4.7uF decoupling caps removed for now.

I can try to add other functionality to `Net.cpp' server, as I hope for
being able to transfer files in the end when proved possible.
