In consensus/src/model/sstores/utxo_set.rs the write_many function will use a DirectDBWriter to write to the UTXOs to the database.

It seems like converting using a WriteBatch to write the data as an entire batch would make this area less hot (See Extras section below)

Writing to cache can also be skipped

TODO

• Investigate if converting to BatchDbWriter indeed results in performance improvements (either faster completion or less CPU intensiveness)
• (if so) Implement a write_many_without_cache, and update UtxoSetStore::write_many to use write_many_without_cache passing in a BatchDbWriter instead of a DirectDbWriter instance
