The SheerVideo decoder uses two VLC tables and these are in turn created
from structures (called SheerTable) that are naturally paired. This
commit unifies these pairs of SheerTables to arrays and unifies creating
the VLC tables.

The SheerVideo decoder uses VLC tables which are currently stored in
large arrays that contain the length of each leaf of the corresponding
tree from left to right, taking 15.5KB of space. But all these arrays
follow a common pattern: First the entries are ascending and then they
are descending with lots of successive entries have the same value.
Therefore it makes sense to use a run-length encoding to store them, as
this commit does. Notice that the length 16 has to be treated specially
because there are arrays with more than 256 consecutive entries with
value 16 and because the length of the entries start to descend from
this length onward.
