Layout for Access Virus C

Marked as draft because there are a few minor details I still want to fix. And also because the LED matrix seems to use some slightly modified scanning method, that identifies the LEDs by coordinates like 1A0, 2B4, etc... The usage of the letters A and B seem to indicate there are two independent LED matrices. The ones with the letter B are mapped just like for Virus A and Virus B. But I have no idea how the ones with the letter A are activated. Maybe an additional port write? Or maybe other bits of those same writes to port 5? Needs more investigation...

Running the strings command on the Virus C ROM we can extract the full list of LED coordinates:

This is how it looks right now:

This is ready for merging. I'll investigate the LED matrix issue and submit another PR once I figure that out, but the layout drawing is considered done:
