* Update MIGRATION_GUIDE.md

Saw one typo, spent a few minutes improving a few paragraphs.

* Moving `DecodeSegement` to `Parser`

This would allow us to remove some global variables and move them to parser options as well as potentially introduce interfaces for json and b64 encoding/decoding to replace the std lib, if someone wanted to do that for performance reasons.

We keep the functions exported because of explicit user demand.

* Sign/Verify does take the decoded form now

This PR adjusts the error checking example so that a check for an invalid signature is also included.

See discussion in #143

…ot an advisable input for key (#249)

* add documentation around Verify & Sign to detail why string is not an advisable input for key

* Refer to the usage guide
