js: transfer encoding changes

--

* Uint8Arrays are not supported for now there are unsolved issues in
  conversion, and they are lower priority

* encrypt gains a new option to indicate that input values are base64
  encoded
* as decrypted values are always base64 encoded, the option base64 will
  not try to decode the result into utf, but leave it as it is
