[BUGFIX] Fix recursion limit when applying large reduce functions (851)

Python would think a recursive error occurred, but in reality, the stack got too large due to poor optimization when executing array reduce functions. Thanks Melissa from Discord for the bug report!

[BACKEND] Add `collection_season_name` variable to collection presets (850)

Can now be used to change directory names for collection presets

[FEATURE] Filter plugins, regex helper script functions (848)

Adds generic `filter_include` and `filter_exclude` plugins in anticipation for function script usage. Will detail it more with official docs at a later time!

[BACKEND] Improved error messages when script resolution does not work (846)

[BACKEND] Validate override variable names (845)

Validate as early as possible whether override names are invalid, to prevent confusing downstream errors

[BACKEND][HUGE] Function Support in variable syntax (838)

A complete gutting of the internals of ytdl-sub to support functions in our variable syntax, in addition to being able to access a yt-dlp entry's .info.json fields using functions. Functionally, ytdl-sub should still look and behave the same from a user-perspective.

With so many lines of code changed (+8927, -2708), no doubt there will be new issues. Please make a GH issue or reach out on Discord if your config/subscriptions break in any way/shape/form.

Details on how to use function support will come soon in the form of proper documentation in our readthedocs.
