fix parquet event processor to handle miss-matching events and event …

[yuunlimm]

Description

Backfilling parquert events on testnet and mainnet was failing due to missing events for validator txn type. Initially thought that events are missing b/c fullnode wasn't up to date. However, it wasn't the case. So, we are making a general rule that event_size_info will work for user_transactions, but no promisses on other transactions.

the new behavior is that if we don't have matching events and events_size_info, we are going to panic and investigate. But for other types, they will be defaulted to 0 size_info. for those txns with missing events that are not user_transactions, we can backfill anytime if needed.
