Installation fails on Windows

[cannam]

I made the schoolboy error of bringing a Windows laptop along with me today, and I thought I'd see how npm gets on with our packages on it. I'm running everything from Powershell (because that is the Windows Way) rather than trying to use the Windows Subsystem for Linux or whatever.

It doesn't work that well, it turns out. Although I could install most of the packages needed by ugly-duckling, piper fails because it explicitly tries to run Unix shell commands:

PS C:\Users\Chris\Documents\ugly-duckling> npm install

Ah, damn. Big oversight from me there.

Left as-is, this would actually work fine for a consumer of piper if I got rid of that "postinstall" script and published this to npm. Or included pre-compiled stuff in the repo which is quite common.

I'll have to script it for a more portable solution. The build process is pretty gross and could probably be simplified.

fwiw, the waves-ui bundle procedure had basically the same problem (it shelled out to "find" to pick up the files to transpile). That was also pretty gross anyway of course. I pushed a fix this morning.
