Initial nostrdb integration (#1393)

This is a rewrite of the codebase. There was no reasonable way to break this into smaller commits, so here it is.

- Switch to nostrdb's NdbNote type instead of NostrEvents
- Much improved typing, Pubkeys are now Pubkeys (raw data) instead of String

This prepares the codebase for the switch over to memory-mapped note data which will live inside lmdb.
