Adapter PCB and snap cover for FluxEngine

Provides both a 34-pin connector for normal 3.5 inch and 5.25 inch drives, and a 50-pin connector for 8 inch drives.

The fpga board may be connected with or without soldering pins or sockets.

The 26-pin rows act as friction-fit connectors that work like sockets without needing to actually install sockets.

You can still solder normally to connect the fpga board permanently, or solder normal sockets.

To use the solderless option:

1. Order the hat pcb with ENIG finish to make the holes gold plated.
2. Solder the 34 & 50-pin connectors and the jumper pins, but leave the two outside 26-pin rows clean.
3. Solder the two 26-pin male pin headers and the 5-pin female socket to the bottom of the fpga board.

Now the fpga board may be attached by just pushing the pins into the staggered rows,

and also removed again any time to use with a different hat, for some other project on a breadboard,

and re-attached again at any time to use for FluxEngine again.

This FluxEngine_Hat supports Shugart-compatible 8-inch drives, which is most 8-inch drives.

On the github repo there are other hats that support CDC drives. (Control Data Corporation / Magnetic Peripherals Inc)

Some CDC drives are Shugart-compatible, but others have other pinouts that are not Shugart compatible.
