Improve script to patch wasm artifacts and load EN->DE vocabulary in wasm test (#125)

* Improved script that patches wasm artifacts to enable wormhole

 - Made the regex pattern ignore multiple whitespaces b/w words of
   the matching pattern

* Fix for loading EN->DE vocabularies in wasm test page

 - Loading vocabularies for EN->DE was failing because of
   the new structure of bergamot-models
