rvcencode: a ZX81 video encoder

ZX81 video encoder
An encoder to convert videos to the RVC-format, playable on the ZX81.
A player for the ZX81 to play RVC files.
RVC = Retro Video compression, Character based
RVC images are 1/6th the size of ordinary hires images. It all comes down to uncomressing the data on-the-fly with the hardware acceleration available, the character set!

The player requires a ZX81 with a ZXpand classic or ZXpand+, together with a UDG4ZXpand or Chroma81 to get 128 user definable characters.
