BSON-v1.0.0 - BSON serialization and deserialization

Changes for version v1.0.0 - 2016-07-06

!!! Incompatible Changes !!!
- Internal representation of BSON::Bool changed to make it a subclass of boolean.pm for conistency with other "boolean" type classes on CPAN.
- All BSON type wrapper classes are now immutable; accessors have been changed to read-only.
*** Deprecations ***
- BSON::Binary deprecated in favor of the new BSON::Bytes module.
- BSON::Bool deprecated in favor of direct use of boolean.pm.
- BSON::ObjectID deprecated in favor of the new BSON::OID module.
- The 'ixhash' option is deprecated in favor of 'ordered' and the resulting tied object is no longer guaranteed to be Tie::IxHash. This will allow future optimization, as Tie::IxHash is extremely slow.
API
- BSON module is now object-oriented, with an API and options directly compatible with the MongoDB driver. Options set as constructor attributes apply to all encoding/decoding, unless options given to methods override them.
- Added a method for inflation of MongoDB's extended JSON format to BSON type wrapper objects.
BSON types
- Added new type wrappers to cover all BSON Types, including forthcoming Decimal128 (but Decimal128 is still considered 'experimental' and subject to change).
- Rationalized/harmonized BSON type classes for compatibility with pre-existing MongoDB BSON classes. Classes that could not be made to interoperate are deprecated as listed above.
Bug fixes
- Fixed numerous encoding and decoding bugs revealed by greater test coverage (e.g. fixes to UTF-8 encoding/decoding).
Testing
- Significantly improved test coverage, including tests using a standardized BSON corpus.
- Skip threads tests before 5.8.5 because of problems with weak references during global destruction.
- Require newer Path::Tiny with full-featured "basename" method.
Prereqs
- Bump boolean prereq to 0.45 to avoid conflicts between some versions of JSON::XS and older boolean.pm releases that had read-only singletons.
- Bump Moo prereq to 2.002004 to work around core sub shadowing bug in generated constructor.
~Internal Changes~
- Pure-perl implementation split into a separate module to avoid its load time in the future when an XS implementation becomes available.
- Will prefer BSON::XS (when released) or fallback to BSON::PP; PERL_BSON_BACKEND environment variable will override.
