Add package.json to make this repo installable from npm

[normanlolx]

I tried to include this repo from npm via

$ npm install git+https://[email protected]:bramstein/hyphenation-patterns.git

which gives me

npm ERR! premature close

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/leymannx/.npm/_logs/2019-04-17T11_28_13_010Z-debug.log

which is due to the repo having no package.json as described in:

• https://github.com/coryetzkorn/state-svg-defs/issues/1#issuecomment-458311603.

Official npm/npm issue:

• https://github.com/npm/npm/issues/20824

Seems some of the forks happened exactly because of that, to add a package.json: https://github.com/fluid-project/hyphenation-patterns/commit/d313a52a3973afc4ed8503a533a0473e5966374e
