Update to base64-bytestring-1.2.0.1

1.2.0.1
* Package update: support for bytestring >=0.11

1.2.0.0
* Security fix: reject non-canonical base64 encoded values - (#38)
  fixing issue #24.
* Security fix: reject bytestrings with improper padding that can be
  "completed" by the unpadded-Base64url workflow, and homogenize error
  messages (#33)
* Test coverage expanded to 98% of the library. All critical paths
  covered.

1.1.0.0
* joinWith has been removed (#32)
* Bugfix: decode formerly allowed for padding chars to be interspersed
  in a valid base64-encoded string. This is now not the case, and it
  is fully spec-compliant as of #31
* The default behavior for Base64url decode is now to support
  arbitrary padding. If you need strict padded or unpadded decode
  semantics, use decodePadded or decodeUnpadded.
* Added strict unpadded and padded decode functions for Base64url
  (#30)
* Added unpadded encode for Base64url (#26).

1.0.0.3
* Made performance more robust (#27).
* Improved documentation (#23).
* Improved the performance of decodeLenient a bit (#21).
