[Innawoods] Welding and plastic molding

[Sathra225]

Summary

Mods "Makes plastic molding possible, plus welding goggles"

Purpose of change

Plastic molding for bottles and the like needed polycarbonate sheets, which aren't craftable. Removed them from the requirement list. Makeshift vacuum molder and sealer also needed uncraftable parts, fixed that. Also made welding goggles craftable from scratch (with glass goggles).

Describe the solution

Replaced polycarbonate sheet in plastic_molding requirement with plastic chunk. Added leather hoses as alternative to rubber hose in makeshift sealer/vacuum molder. Made vacuum pump + makeshift drivebelt autolearn (belt is needed for vac pump). Added glass goggles to welding goggle recipe as another alternative to the base goggles.

Describe alternatives you've considered

Removing material cost entirely for plastic_molding and updating recipes for increased components.
Figuring out some craftable thermoplastic variant to use instead of polycarbonate. Same with making rubber hoses craftable.

Testing

Made changes, recipes unlocked at correct skill levels. Game didn't crash or throw errors.

Additional context

Items that use the plastic_molding requirement look a bit strange with plastic chunks listed twice, but ultimately harmless. Welding goggles still use plasticworking proficiency even though they don't need any plastic now, but changing that would necessitate adding a new recipe.
