[web-nfc] Pull Request: As event listeners cannot have side-effects, intro start/stop

kenchris has just submitted a new pull request for https://github.com/w3c/web-nfc:

== As event listeners cannot have side-effects, intro start/stop ==
This follows the Generic Sensor approach, except `start` returns a promise which
can be fixed in a future PR.

See https://github.com/w3c/web-nfc/pull/183
