v2.0.4-alpha.0

New features:

• Do not unnecessarily copy read data in BinaryReader, see #148
  Note that it is now strictly necessary to respect the offset of the underlying buffer
  of byte fields.
• Add force_exclude_all_options plugin option, see #126
  Thanks to @optiman for the suggestion.

Bug fixes:

• The new symbol property MESSAGE_TYPE broke user unit tests. The property was set to non-enumerable.
  Thanks to @jcready for the feedback.
