Add skip list based implementation for smaller encoding

This arranges for the sparser sets (everything except lower and uppercase) to be
encoded in a significantly smaller context. However, it is also a performance
trade-off (roughly 3x slower than the bitset encoding). The 40% size reduction
is deemed to be sufficiently important to merit this performance loss,
particularly as it is unlikely that this code is hot anywhere (and if it is,
paying the memory cost for a bitset that directly represents the data seems
worthwhile).
