load fail on script load, looking for we Polysub

[xmacex]

I am getting "error: load fail" on script load. This from Maiden

# script load: /home/we/dust/code/fretwork/fretwork.lua
### SCRIPT ERROR: load fail
/home/we/dust/code/fretwork/fretwork.lua:8: module 'we/lib/polysub' not found:
	no field package.preload['we/lib/polysub']
	no file '/home/we/norns/lua/we/lib/polysub.lua'
	no file '/home/we/norns/lua/core/we/lib/polysub.lua'
	⋮

The script is looking for Polysub engine in the we library. The library was depracated in a recent norns update, and all scripts which require stuff from the not extinct we library need an update. This is a known issue.

The fix is simple, and a pull request coming up in a sec.
