PXT package.json dependencies - some might actually be needed at dev time only?

[jfo8000]

Just saw this - might be intended but there are a few libs that are usually only used during the build/testing process.

Might be alright since it is a build tool? Just double checking cause it's the kind of thing I'd accidentally do. If not used at runtime they can probably move over to devDependencies.
