Feature parity of the new parser

[V0ldek]

Short description

New parser replacing all old parsing logic.

This is not release-ready, there is a few cleanup tasks left:

• update fuzz and prop tests
• consolidate parsing tests to occur only in the syntax crate and not in lib
• verify documentation

Unfortunately, this breaks some queries (those asking to match control characters). Look to #117 for tracking.
