Add recommended 24MHz crystal setting
Later, we should check if we can reduce the bias, also (For me, it works with minimal bias -but I think should should keep it for now, as it is).

There were some issues in the setRX and setTX functions for T4,x
It never came up much with T4 as there were not really alternative pins...
But fixed and tested with simple sketch on T4.1 and simple jumper to TX and RX pins on memory chip locations

T4.x CTS pins - T4.1 add memory chip area to Serial ports.
A few of the T4 and now T4.1 Serial ports support a CTS pin. One was previous fixed, added the others to tables.
Also T4.1 has Some Serial port pins in the area that the optional memory chips could be installed

Update RAW HID TX buffer to be in DMAMEM
Decided to go ahead and move the TX Buffer there as well
Did a quick check in earlier test program to echo the contents back.
The other test program was already setup to receive data on the HID and does hex dump of buffer which looks correct. So far so good.
