flashsvenc: replace bitstream description by a link to the specification

An official specification now exists and it is both more detailed and
easier to understand than the incomplete notes available here.

- *  4 bits of block width
- * 12 bits of frame width
- *  4 bits of block height
- * 12 bits of frame height
- *
- * Directly after the header are the compressed blocks. The blocks
- * have their compressed size represented with 16 bits in the beginning.
- * If the size = 0 then the block is unchanged from the previous frame.
- * All blocks are decompressed until the buffer is consumed.

  * Encoding ideas: A basic encoder would just use a fixed block size.

  * have to be quadratic. A brute force search with a set of different
