Package Module Sharp should be a dep and not a dev-dep

[gbourne1]

The image.js file uses Sharp, so there is a runtime error because Sharp is only a dev dependency.

Suggest moving to dependency.

Error: Cannot find module 'sharp'
Require stack

Sharp is actually a peer dependency and kind of needs to be. Having different versions of Sharp in the same top level node app with different backing libvips binaries can cause issues.
