Add support for PulseChain snapshots
This branch implements support of btree indexes instead of .kvi files.
Kvi also created, but not used during search/lookup, only for size
comparation.
Btree allows to make seek calls, while recsplit indexes does not support
that query.
During initial tests, btree indexes are ~1-3% smaller than recsplit but
avg lookup time bigger up to 1.5us (which compensates with ability to
fetch next key).

Currently the only way the `noProgressCounter` resets is when it
discovers that the chain has forked from the cannonical chain which
leads to lack of anchor state logs.
