Modified: RX running on only one state machine and TX without the need of program overriding

[ghost]

I tried to modify the RX and TX PIO programs so that there is only one state machine running for RX and the TX programs don't have to be overrided when changing speed, changing pin order or sending pre-token:

Maybe there is an advantage of performance but at least i didn't realize any disadvantages.
It worked for me in a midi interface consisting of 4 USB root ports and one (regular) device port.

So maybe someone wants to try it out and tell about the results?
(It should be compatible with the original version.)
