Additional percent-encode sets

[cryptoquick]

I've added some additional constants that should be useful for others.

I'd also recommend adding #721.

I've also corrected some docs generation warnings.

These sets are duplicated across percent_encoding and url/src/parser.rs now.

Can you de-dupe?

Good point! Will do.
