foundation-sites: Typings file not detected

What should happen?

The typings file should be detected.

What happens instead?

Receiving errors that the typing file cannot be found and should declare one

ERROR in src/client/foundation.ts(23,21):
TS7016: Could not find a declaration file for module 'foundation-sites/js/foundation.orbit'. 'node_modules/foundation-sites/js/foundation.orbit.js' implicitly has an 'any' type.
  Try `npm install @types/foundation-sites` if it exists or add a new declaration (.d.ts) file containing `declare module 'foundation-sites';

Possible Solution

Unknown. Typings file does exist but not being picked up for some reason.
