RUSTSEC Warnings and Errors on several subprojects

[Pi-Cla]

I rancargo audit on every submoduled project and a bunch of them have various RUSTSEC vulnerabilities and warnings. All of these except for one at the end of this list was fixed by simply running cargo update. I think making an issue here might be better than making a separate issue in every submodule github repo?
