Incorporating mkcert as a certificate manager for Hetty.

[Lawri-van-Buel]

For the start of this see Pull request 21

Basically the idea is to use Mkcert as a library for managing the root CA and it’s installation, freeing up Hetty to do the proxy bits (keeping in line with the philosophy of doing 1 thing but doing it really well.

We can even offload some of the current parts dealing with x509 generation to the library.

I would love to get other peoples insides into this idea before anyone starts working on it.
