get Helio Workstation working to some stage

[atsushieno]

apart from https://github.com/atsushieno/aap-juce/issues/6 I wanted to have a working DAW, which is like an ultimate goal towards 1.0 release.

Helio is based on JUCE, and it supports Android, so I ended up to add AAP support on it and created a repo as aap-juce-helio. At this state, helio can list up AAPs, and it seems able to instantiate them. Though it is still not "working", especially in that:

• the plugin listing is weird. It is rather a helio issue (text too big, without wrapping)
• no audio output port is recognized, so it is simply impossible to connect to audio out and emit any sound.

I would visit this issue on occasion.

Fixed those issues (in AAP) and it's technically working. The audio quality is not great yet, but we can close this particular issue so far.
