Rebased version of https://github.com/haskell-github-trust/thyme/pull/45.

Needs further evaluation of:

1. the scanner dependency, should we pickup an additional dependency and is the package well enough maintained to choose.
2. Run more benchmarks on recent GHC versions and compare against attoparsec

Benchmarks on macOS 12.6.3, GHC 8.10.7, 2.3 GHz Quad-Core Intel Core i7:
