Chord.detect does not recognize 7th chords without 3rds

[biowaffeln]

For example, given a chord of ['C3', 'G3', 'B3'], I would expect Chord.detect to produce ['C5maj7'] as an output, however it gives me an empty array:

import { Chord } from 'tonal'

Chord.detect(['C3', 'G3']) // ['C5']
Chord.detect(['C3', 'E3', 'G3', 'B3']) // ['Cmaj7']
Chord.detect(['C3', 'G3', 'B3']) // [], but should be ['C5maj7']
Chord.detect(['C3', 'G3', 'Bb3']) // [], but should be ['C5add7'], or possibly ['C5/7']

For the Chord.detect(['C3', 'G3', 'Bb3']) case you'd have to decide on some sort of notation to keep the numbers separate. I think either C5/7 or C5add7 would be fine.
