Consider using non-rustls types in the API about rustls-native-certs

Plus rustls could have like a TryFrom impl for whatever type you use here?

I'll probably need to hoist the PEM code out of rustls to achieve this. But that seems like a good idea.

This is currently making it difficult to have a git dependency on rustls, which causes problems like quinn-rs/quinn#805.

👍 I wanted to use this crate with reqwest's rustls mode and call add_root_certificate but reqwest has its own certificate types which abstract over the various backends, so the rustls types aren't helpful here. I guess reqwest doesn't want to become dependent on the version of rustls so it'll likely not want to expose compatibility with rustls types in the API.
