Function durationToBeats

durationToBeats(
duration: NoteValue | DurationData,
options?: { beatUnit?: NoteValue | DurationData },
): number
Length of a written duration in beats.
Parameters
- duration: NoteValue | DurationData
  The duration, or a bare base value as shorthand for an undotted one.
- options: { beatUnit?: NoteValue | DurationData } = {}
  beatUnit sets what one beat is; a quarter note by default, so a dotted quarter reads as 1.5. Pass { base: 'quarter', dots: 1 } to count in the felt beats of a compound meter.
Returns number
The length in beats.
Throws
If the base value is unknown, the dot count is not an integer in 0..4, or a tuplet side is not a positive integer.
Example
```
import { durationToBeats } from '@libraz/libcantus';
durationToBeats('quarter'); // 1
durationToBeats({ base: 'quarter', dots: 1 }); // 1.5
durationToBeats({ base: 'eighth', tuplet: { actual: 3, normal: 2 } }) * 3; // 1 — three
// eighth-note triplets fill the beat two eighths would
```
