Alternative quality mechanics using the continuous spoilage mechanic. [ALPHA]

Quality is represented as the spoilage fraction of items. To increase quality, use Quality Assayers and Quality modules to produce Quality Controls, that increase the quality of your products.
To use your items, you must first place them in a Quality Converter Chest. This is a chest that converts its items to the usable vanilla version. (that doesn't spoil. This only affects items that are used outside of recipes, ingredient-only items are not converted.)

(every recipe now requires Quality Controls, this can easily fixed by simply placing a Quality Assayer next to any assembler)
Quality Controls is a jank mechanic yes, but it was the only way I could make Quality Modules increase the freshness of items.
Quality assayers have several QOL features. Like: Quality modules are automatically reinserted, Quality Controls are automatically placed into nearby machines. So you don't need any inserters.

Quality conversion acts like this:

>90% spoiled = Common
<90% spoiled = Uncommon
<70% spoiled = Rare
<40% spoiled = Epic
<5% spoiled = Legendary

Warning: This is jank, unoptimized, and probably has some edge case exploit I haven't thought of.

Planned Features:
QoL - Make as many items as possible usable without having to explicitly convert them.
Quality weighting - Make certain recipes more dependent on manufacturing quality and some more dependent on ingredient quality.
Ore preparation - Gaining high quality ore will be easier than most other ingredients due to special ore-washing recipes.
Compatibility with extra quality mods - Do you want 255 quality levels? Go for it.
Balancing - Uncommon science at start is pretty OP, who could have guessed?
