TonedScale(tonic="Sa4", system="indian") now works — no need to
import SYSTEMS. Same for Key("C", "major", system="blues").
Updated README and all docs to use the cleaner string syntax,
removing 'from pytheory.systems import SYSTEMS' boilerplate.

Key class — the friendliest entry point for music theory:
Key("C", "major").chords → all diatonic triads
Key("C", "major").seventh_chords → all diatonic 7th chords
Key("C", "major").progression("I", "V", "vi", "IV")
Key("C", "major").relative → Key("A", "minor")
Key("C", "major").parallel → Key("C", "minor")
Note = Tone alias for discoverability.
README rewritten to showcase the full API:
tones, scales, diatonic harmony, chord analysis,
6 systems, 25 instruments, audio playback,
comprehensive feature list.
381 tests.
