Load Tracks of Other Durations

[StatsBen]

It would be nice if Macaron could load WAV files that are not exactly 3 seconds long.

Currently, Macaron parses the data in a WAV file of other lengths, but anything over the 3 second mark gets discarded as keyframes outside the desired time range. A better version would simply adjust the length of the editor window to the length of the loaded track.

x-posting my slack message here in case it's helpful:

There are three levels of ways to fix the duration problem (from fast to done right):

1. Quickfix: hardcode-change the timeline to be 5 or 7 or 10s
2. Moderate fix: Add a text field to change duration of the editor
3. Done right: infinite timeline w/ zoom (I think, will need to do some design work)
