avcodec/qdm2: Make tables used to initialize VLCs smaller
After permuting the codes, symbols and lengths tables used to initialize the VLCs so that the codes are ordered from left to right in the Huffman tree, the codes become redundant as they can be easily computed from the lengths at runtime (or at compile time with --enable-hardcoded-tables); in this case one has to use explicit symbol tables, but all the symbols used here fit into an uint8_t, whereas some codes needed uint16_t. Furthermore, the codes had holes because the range of the symbols was not contiguous; these have also been removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
