Replace the numeral package with ~30 lines of int2roman()/roman2int()
in _statics.py. Reduces supply chain surface. Fixes#47.

Smoothly sweep any parameter (lowpass, reverb, distortion, etc.)
from current value to target with linear, ease_in, ease_out, or
ease_in_out interpolation curves.

Part.crescendo(), Part.decrescendo(), Part.swell(), and Part.dynamics()
for velocity ramps and custom curves across note sequences.

Duration enum now supports multiplication, division, and addition
so expressions like `Duration.WHOLE * 2` work instead of raising TypeError.

- Replace pytuning with 30-line native implementations of EDO,
Pythagorean, and quarter-comma meantone scale generators
- Lazy-load scipy.signal (337ms) — only imported when audio rendering
is actually used, not on theory-only imports
- Removes pytuning and sympy from dependencies entirely
Import time: 0.479s → 0.056s (8.5x faster)
Closes#44

- Drums are real Parts with full effects pipeline
- split=True creates kick/snare/hats/toms/cymbals/percussion Parts
- Sidechain triggers on kick only
- Score.from_midi() imports Standard MIDI Files
- Document split drums workflow

Load any Standard MIDI File into a Score. Zero-dependency parser
handles Type 0 and Type 1 files. Each channel becomes a Part,
channel 10 becomes drum hits. Roundtrip with save_midi works.

All 15 drum sounds rewritten with inharmonic partials, proper
transients, multi-mode resonance, and saturation. Song #19:
Dance Party at the Reitz House — for Sarah and Malachi.

Different comb filter delay times per channel create natural stereo
width in the reverb tail. Effects chain skips mono reverb in favor
of stereo reverb applied in the mixer after panning.

Feed-forward compression (threshold=0.5, ratio=4:1) with envelope
following, makeup gain, and brick-wall limiter at 0.95. Replaces
simple normalization. Everything sounds louder and punchier.

sounddevice is now only imported when actually playing audio through
speakers. All other functions (save_midi, render_score, save) work
without PortAudio installed. Fixes 9 test failures in CI.

Makes programmed parts feel like a real player. Random timing jitter
and velocity wobble applied at render time, score data stays clean.
