TypeScript support

[patrickberkeley]

Thanks for this library! Are there any plans for TS support either by converting to TS, or publishing type declarations?

Bump on this, I would also be interested to hear peoples thoughts on how they use this addon in combo with TS

Just to add onto this, I created an initial PR for converting the addon to Typescript. It's functional, but missing proper types for any of the breakpoint getters - they're added to the service at runtime from queries provided in the breakpoints.js file, so I'm not sure the best approach for typing them
