Add temp as direct dependency

[sporto]

See https://github.com/elm-community/elm-webpack-loader/issues/200

"temp" is in the package-lock.json But when running this without elm-test in the same project I get this issue above

Error: Cannot find module 'temp'

As temp is used directly here: https://github.com/elm-community/elm-webpack-loader/blob/2bbe487e654231e3531374747c23043b8f440a44/index.js#L5

I believe it should be as a direct dependecy in package.json

Thanks

I'm seeing this issue as well. Adding this to my package.json fixed this for me.
