chord added and corrected

Description
'arp-pow': { intervals: [4], name: 'fifth (powerchord)' },
should be like this because semitone 4 is major 3rd interval
'arp-pow': { intervals: [7], name: 'fifth (powerchord)' },
also some of extended chord like 13th, 11th, you define it with 9th note while the name is not contain 9th
Implementation details
will send the full correction if you interest
thanks

Nice catch, this has been corrected.

Those are extended chords. If you add the 11th/13th but not the 9th, it's called an added tone chord. I could add those too if you think they'd be useful.
I wrote some tests for the arpeggios on the develop branch, all of them should be correct now. Feel free to reopen this issue if you notice another mistake.

added tone chord is extended chord (semitone > 12) without seventh (semitone 10) or major seventh (semitone 11) e.g.
'arp-majadd9': { intervals: [2, 4, 7], name: 'major added 9th' },
in music theory the chord should be like :
'arp-min11': { intervals: [3, 5, 7, 10], name: 'minor 11th' },
'arp-min911': { intervals: [2, 3, 5, 7, 10], name: 'minor 9th 11th' },
'arp-dom11': { intervals: [4, 5, 7, 10], name: 'dominant 11th' },
'arp-dom911': { intervals: [2, 4, 5, 7, 10], name: 'dominant 9th 11th' },
'arp-maj11': { intervals: [4, 5, 7, 11], name: 'major 11th' },
'arp-maj911': { intervals: [2, 4, 5, 7, 11], name: 'major 9th 11th' },
this formula work on 13th chord too
seems dont have suspended chord too, sus2 and sus4 variant, thanks
please review it first, chord ref are from wiki or wikibooks
not sure about extended chord for augmented and diminished, still investigating
thanks
