Instrument catalog

Every voice in @spacedevin/deck-synths, generated from generatorCatalog() and defaultParamsForGeneratorId() so it cannot drift from the code.

Select one with track <Name> id <id> gen <generatorId>. Parameters are set with gen <key> <value> in snake_case — sweep_amt 26 reaches the voice as sweepAmt. Values below are the defaults.
