v2.0.0

First release of normalasser! But this is just a continuation of normalize-ssa, modernized for current expectations. Static dependencies are removed, parsing will not overwrite subtitles without --force-mkv, file operations are atomic, webhooks for Radarr and Sonarr are added, and normalasser is available as an alpine-based docker image. And a normalization issue that could cause the wrong primary style to be selected has been fixed!
