* Fix a resource leak introduced in https://github.com/status-im/nimbus-eth2/pull/3279
* Don't restart the Eth1 syncing proggress from scratch in case of
monitor failures during Eth2 syncing.
* Switch to the primary operator as soon as it is back online.
* Log the web3 credentials in fewer places
Other changes:
The 'web3 test' command has been enhanced to obtain and print more
data regarding the selected provider.
* log doppelganger detection when it activates and when it causes missed
duties
* less prominent eth1 sync progress
* log in-progress sync at notice only when actually missing duties
* better detail in replay log
* don't log finalization checkpoints - this is quite verbose when
syncing and already included in "Slot start"
* 3x speedup in snappy compression
oh, the wonders of `copyMem` in `endians2` - speeds up all kinds of
operations like database stores, sending gossip etc.
* endian usage fixes
* ncli_db: add putState, putBlock
These tools allow modifying an existing nimbus database for the purpose
of recovery or reorg, moving the head, tail and genesis to arbitrary
points.
* remove potentially expensive `putState` in `BeaconStateDB`
* introduce `latest_block_root` which computes the root of the latest
applied block from the `latest_block_header` field (instead of passing
it in separately)
* avoid some unnecessary BeaconState copies during init
* discover https://github.com/nim-lang/Nim/issues/19094
* prefer `HashedBeaconState` in a few places to avoid recomputing state
root
* fetch latest block root from state when creating blocks
* harden `get_beacon_proposer_index` against invalid slots and document
* move random spec function tests to `test_spec.nim`
* avoid unnecessary state root computation before block proposal
* add merge SSZ consensus object tests
* add merge attestations, attester slashing, proposer slashing, and voluntary exit test fixtures
* throw catchable exception rather than assert on invalid SingleMemberUnion selector
* hash_tree_root can assert, because it's trusted data by that point
* re-assert on writing, since also trusted data
* beta.4 update
* implement upgrade_to_merge()
