Combine TSParser and TSStateMachine objects
...
My original thought was to decouple the runtime from
the LR parser generator by making TSParser a generic
interface that LR parsers implement.
I think this was more trouble than it was worth.

Store ParseItemSets as maps, w/ core items as keys
...
ParseItem no longer has a lookahead_sym field; it now represents
the 'core' of a parse item. The lookahead context is stored separately,
as a set per core item. This makes iterating, copying and merging item
sets more efficient, because before, the core items were repeated for each
different lookahead symbol.
Also, the memoization in sym_transitions(ParseItemSet) has been removed.
Maybe I'll add it back later.
