Add Section on ZKEmail

[adrianmcli]

From Ayush:

For context for education, we do have a zk lecture that might be fitting! Specifically it's a one and a half hour onramp from basic set membership proofs all the way up to zkemail (zkiap.aayushg.com)

For uni students, more simple end to end crypto projects will be highest return. We have various project lists at aayushg.com/ideas > crypto (broader crypto ideas) and github.com/zkemail > ideas

Apart from zkiap.com, I've found many students internationallly don't know about basic courses, libgen, or scihub which are all critical

I.e.
6.857, applied cryptography, basic blockchains and hashing and zk: https://courses.csail.mit.edu/6.857/2022/handouts (only notes, no videos)

6.875, advanced theoretical cryptography guiding up to zk and lattices: http://mit6875.org/
