implementation of createMime function to transfer images.

[spsingh559]

Hi team,

Is it possible to support MIME data type (Images) apart from TEXT and URI. There is already reference given by android NFC here https://developer.android.com/reference/android/nfc/NdefRecord#createMime(java.lang.String,%20byte[])

It's of course nice-to-have. You can open a pull request about that, because adding this feature seems to be trivial. If not, I think I will add this feature in some near future.
