sts::Hitfinder: Replace asserts with monitor struct.

Adds monitor-struct to sts::Hitfinder. Removes obsolote asserts and replace required asserts with monitor counters instead.

Note: sts::HitfinderChain contains a bunch of aborts. However these are only used during debugging and can't be triggered in production.
