Adds size standardization bracelets to protolathe (#6751)

## About The Pull Request

Adds size standardization bracelets to the protolathe, giving them an
in-game method of being made, instead of requiring admin spawn or
loadout equip. I made the recipe kinda cheap because it's mostly a fluff
item / makes life less of a living hell.

## Why It's Good For The Game

seems useful for events and / or just general purpose.

## Changelog
