Collapse the various standalone functions for parsing block data, and
refactor consumers to initialize a Block with given data and access its
members as needed.

This is a refactor of the codebase to use a more memory-efficient
representation of notes. It should also be much faster at decoding since
we're using a custom C json parser now.
Changelog-Changed: Improved memory usage and performance when processing events
We eventually want to switch over to NdbNote instead of NostrEvent. To
facilitate this, the plan is to eventually make NostrEvent an alias of
NdbNote. For this to work, let's make sure the NostrEvent extensions are
implemented on NdbNote.
We will likely switch away from string properties as well, but for now
we will try to emulate as much as possible to make sure everything is
working first.
