Not all scripts in this repo are self-contained

[simonvanderveldt]

I noticed some scripts in this repo have external dependencies.
For example the scales demo as well as several of the studies have a dependency on Polyperc, see
https://github.com/monome/we/blob/master/demos/scales.lua#L39

I was wondering how we want to handle this?
IMHO it would be better if the examples in this repo have no external dependencies.

Troubleshooting a norns user on lines today and came up with this problem. demos/scales.lua needs Polyperc and this user did not have awake installed for some reason.

Update the example to use PolySub instead?

polysub is going to eventually also moved out of we

better fix is to just note the requirement in the comment text for now. we need to have more robust error messages for missing engines.

as a general note: not all scripts/repos are going to be self-contained, and will very commonly require engines from another repo.
