date-fns and react are included as dependencies for people only using the core package

[MatthewStanciu]

I recently added a lightning time clock react hook as part of a sub-package @purduehackers/time, called @purduehackers/time/react. This package requires react, @types/react, and date-fns.

I didn't think before merging and I accidentally made it so that users only using the core package @purduehackers/time now have these three dependencies added to their bundle. It's baaaad that this package now forces people to install React when they just want to convert to lightning time 😭

#20 somehow introduced hard links, which prevented it from being published to npm :(
