This is a production release of go-codec.

Changes include:

• support EncodeOptions.NoAddressableReadonly option
• streamline/reduce size of helper types
• optimize side(En|De)code and (En|De)codeExt calls
• decode a number from any number in the stream i.e. you can decode a float/integer/unsigned integer from any number in stream
• clean up tests so they work completely regardless if we recover from panics
• improve inlining of common functions

Please try it out and share your experiences.
