Restructure library

[survived]

CGGMP21 DKG has been proved to be UC-secure, and thus it can be safely reused with other UC-secure TSS implementations. To make it reusable, this PR moves DKG implementation into separate crate cggmp21-keygen, and key share definition into separate crate key-share

Did you forget to remove keygen files from cggmp21/? It seems they are no longer part of the module tree
