std::fma not necessary with proper compiler options.

AIS decoding and really bad UI.
...
The decoder needs a serious refactoring/decoupling.
The UI just dumps bits of the received packets into a console window, whcih scrolls too quickly in an AIS-dense area with a good antenna.

CRC class.

Has some more efficient code, commented out because I was having trouble getting it to work. However, it may have been due to the particular data I was trying to decode and CRC-validate.

This addresses issue #61 , occasional FIFO/data corruption. With the mutex, any thread on one core can write to the FIFO. But still, only one thread on one core should read from the FIFO.
