Allow installs on windows by no-oping functions

[hertzg]

Is your feature request related to a problem? Please describe.
Due to hard restriction in package.json for win32 library users either need to add the package to optionalDependencies and deal with conditional imports or just ditch the package all together.

Describe the solution you'd like
Allowing installs but performing a "no-op" operation on unsupported methods would provide much better experience.
