Mimeograph-Crumble

First, an enormous amount of gratitude to the authors of cookie crate, Sergio Benitez and Alex Crichton.

mimeograph_cookie is a copy of cookie with:

• All features removed
• HashSet removed
• Cookie Expires is gone (needed the time crate).

The modifications saved 41,852 bytes with a release WASM build.

For documentation, see the cookie crate.

no_std + alloc

All functionality in the crate supports no_std + alloc. To enable, simply disable the default features.
