Add release-tag naming-scheme fields (resolution, source, codecs, group)

Match now also parses filename-only release-tag text - resolution, source
(BluRay/HDTV/WEB-DL/...), video/audio codec, and release group - via a new
guess_release_info() in renamr-core's matching module, wired through a new
guess_release_info Tauri command and called alongside the existing TV/movie
guess for every file. Naming schemes can now reference
{resolution}/{source}/{video codec}/{audio codec}/{release group}, or
FileBot's own short names ({vf}/{source}/{vc}/{ac}/{group}).
