rework epoch cache referencing
* collect all epochrefs in specific blocks to make them easier to find and to avoid lots of small seqs * reuse validator key databases more aggressively by comparing keys * make state cache available from within `withState` * make epochRef available from within onBlockAdded callback * integrate getEpochInfo into block resolution and epoch ref logic such that epochrefs are created when blocks are added to pool or lazily when needed by a getEpochRef * fill state cache better from EpochRef, speeding up replay and validation * store epochRef in specific blocks to make them easier to find and reuse * fix database corruption when state is saved while replaying quarantine * replay slots fully from block pool before processing state * compare bls values more smartly * store epoch state without block applied in database - it's recommended to resync the node! this branch will drastically speed up processing in times of long non-finality, as well as cut memory usage by 10x during the recent medalla madness.
