Command additions to manipulate CAs

[BastienFaure]

Hello,

I was developing a tool on my side to list and inject CAs on the various flavors of Android. But eventually I remember this awesome project who does pretty much related to APK unpinning and figured it would be best to just add two commands list-cas, inject-ca. I know it's a little glitch from the original philosophy of the tool that revolves around APK work, but since you have the ADB bridge cleanly integrated I figured I'd add it here ?

I'm working on a PR, but I'd like to get the author(s?)' opinion about it ?

Since the goal is usually traffic interaction, it seems important to me to be able to deal with CAs as well as pinning inside the APKs anyways.
