A generic ParseError is not sufficient for informing users why their email is invalid.

In most cases a NotFound variant gives too little information.

possibly include a character index where the parsing failed.

Did a lot of work on master. Descriptions are longer. Descriptions include the type of content that was sought. Some errors wrap deeper errors so you can see a chain of causes. Invalid body characters are described better. With usage, we shall see if this is sufficient and helpful.
