Changelog for tagged-binary-0.2.0.1

0.2.0.1

Removed Default instance on TagFingerprint in favor of just a normal emptyTagFP function. This is a breaking change, and is the reason for the "major" version bump.
Fixed bug on decoding badly formatted binary due to unexpected laziness.
Removed dependency on data-default and spoon packages.
Removed upper version bounds for all dependencies except for base.

Tagged ByteStrings now lead with a "TagLead" byte sequence that signifies that a Tagged is coming. For now, it is statically 0xfe 0xff, which are two bytes that are never found in any valid UTF-8 encoded string.
So that all TagFingerprints should be of the same length, TagFingerprints contain an MD5Digest, generated from the name of the type. Its Default instance is the MD5Digest of an empty string.
