Dead link to Mizaru code in documentation

[Shnatsel]

http://geph.io links to the wiki for a description of Mizaru:

https://github.com/geph-official/geph4/wiki/Mizaru-(WIP)

which in turn links to the source code, but clicking that link results in a 404.

I believe the wiki it should link here instead: https://github.com/geph-official/geph4-libs/blob/master/mizaru/src/keypair.rs
