Function spellPitch

spellPitch(
    pitch: number,
    tonic: NoteLike,
    key: KeyLike,
    context?: SpellingContext,
): NoteData
Spell a MIDI pitch relative to a key, keeping its octave.

The octave-less sibling of this function, spellPitchClass, is enough for chord and scale spelling; this one is for naming actual sounding pitches (a generated line, an imported track) without losing the register.

The octave is the one that reproduces pitch from the chosen spelling, so a context that changes the letter changes the octave with it: MIDI 60 spelled B# is B#3, not B#4.
Parameters
- pitch: number
  The MIDI pitch; rounded to the nearest integer.
- tonic: NoteLike
  The spelled tonic of the key, as a note name, a MIDI number, note data, or a Note.
- key: KeyLike
  The key/scale, as a key name, a key/scale, or a Key.
- Optionalcontext: SpellingContext
  Optional surrounding evidence, weighed exactly as spellPitchClass weighs it.
Returns NoteData
The spelled note, carrying the octave that reproduces pitch.
Throws
If tonic does not sound the key's root pitch class.
Example
```
import { spellPitch, formatNote, parseNote, majorKey } from '@libraz/libcantus';
formatNote(spellPitch(70, parseNote('Eb'), majorKey(3))); // 'Bb4'
```
