v0.3.0 - Major Release

This release brings large improvements over the prior releases! The code base is now fully tested with 98% test coverage 🎉

I am much happier with how a lot of things are now so I don't expect there will be any further breaking changes to the API from here on out. In the future i plan to look at adding more data types as-needed and some additional target buffer types.

The notable additions to this release are:

• double/float APIs
• Further implementations of the ReadCountLE/WriteCountLE ReadBytes/WriteBytes APIs
• Several bug fixes from @NaokoAF around the stream wrapper.
• More optimizations, the largest optimization being for the 24-bit int APIs with there being up to 6x speed up in most cases.
• Compatibility with both .net standard 2.0 and .net standard 2.1 (standard 2.0 will not have the ReadCountLE/WriteCountLE stream api due to the implementation relying on the stream span read/write overloads in 2.1)
