Add TMT (T's Musical Tools) plugin

Adds TMT v2.2.0 as a git submodule to Cardinal.

TMT is a collection of esoteric VCV Rack modules focused on
manipulating RNG and polyphonic signals, including:
- Shuffle: Randomly re-order polyphonic channels
- Calendar: LFO-like CVs synced to system time
- Seed: Generate 16 random voltages from a seed
- Ouroboros: Step through polyphonic channels as sequence
- Append: Combine multiple polyphonic cables
- Sight: Non-linear time scale scope
- Spellbook: Plain text RhythML sequencer
- Page: Spellbook expander for columns 17-32
- Stats: Statistical functions on polyphonic signals
- Sort: Sort and select channels using CV control
- Spine: Common voltage offsets and transformations
- Blankt: Resizable blank panel
