Example setup code bug
The code was doing:
pinMode(slaveSelectPin, OUTPUT);
pinMode(slaveSelectPin, HIGH);
Second pinMode should be digitalWrite

Allow setMISO/setMOSI/setSCK - after begin
Made the SPI code work like the old stuff where you could set the miso/mosi/sck pins after the begin.
Some people actually used this for changing SPI on the fly to use multiple sets of pins

Enable Pins - can set more options
The current table code was setup that when we choose a specific pin for MOSI or Miso or SCK (or CS), that the only thing set at the time was the MUX value.
Well the old enable_pins that was called off of the enumlated register was setting the PORT_PCR_DSE option on pins 11 and 13...
So to fix it, I have the table, allow you to fully set the options for each pin.
Still have most all of them just setting the MUX, but do have pins 11 and 13 setting the PCR_DSE option to be compatible with old code.

Turning on the PUSHR_CONT removes gap
Experiment with making the whole transfer of the buffer act like it is
to logically hold the CS pins for that whole transfer. This removes
gaps between each 16 bit transfer.

SPI Transfer(buf, cnt) use FIFO 16 bit
Update SPI.transfer(buf, cnt) to use the FIFO queue to speed things up.
It also speeds things up to pack the data into 16 bit transfers instead
of 8 bits.
As this code is more complicated, no longer makes sense to inline it,
so functions moved from .h to .cpp files.
SPI1 and SPI2 transfer functions were updated as well for T3.5 and T3.6
