Created infrastructure that allows the usage of the serial device to capture the result of the tests.
Then the test is executed agains a pre-defined number of cycles and the result is compared against expectation.

This makes it possible to select CBG or DMG mode taking into consideration the CGB flag in the ROM file.

With initial approach for scalling down the speed of other components.

Created more panic conditions for the KEY0 and KEY1.

The background attributes seem to be failing.

Will allow much better debug.

Allows for more flexibility passing command line arguments.

Still pending processing and conversion to RGB8888.

Still requiring a lot of operational work to allow proper working.

The code now breaks if pedantic is set and a warning is triggered.
