Remove musical instrument bits from nanofab, have instruments directly craftable

[Roomba]

Making a musical instrument out of custom materials in the nanofab is one of the most time-consuming tasks in the game, for pretty much no reason. For the most part, anyone who enjoys figuring out the recipes has already derived all possible enjoyment from doing so, and even they don't end up doing it much because it still takes a metric ton of materials and time and fiddly bits. It's way too much of a chore just for a soulsteel saxophone that plays itself, or a golden fiddle to complete your Faustian bargain kit.

Remove the million fiddly instrument bits and multi-step process to make a custom instrument, and just have instruments directly craftable with a single button press.
