Divorce biome lib and cleanup code (#11)

* make it boot without biome lib

* make luacheck semi sane

* make fast growth saplings work

* make fast saplings respect nodes there growing on

* make regualr saplings work

* fix some luacheck warnings

* add github actions for luacheck

* bump luacheck line limit, as to gracefully handle long tree rules

* switch over to inline luacheck length rules

* fix screenshot warning

* make tree generation work

* add settings from last night

* comment out new biome lib nonsense added

* tune spawning to be better

* turn down fallback ratio

* translate new abm patch to not use biome lib

* add ethereal since its still behaving badly :(
