Support rustls #18
Description
Is your feature request related to a problem? Please describe.
This is the last and only crate in my application which is not supporting rustls. Only for this crate I must include the openssl dependencies.
Describe the solution you'd like
As far as I can tell, all your dependencies already support rustls, so its mostly a matter of adding another feature "rustls" in the same way crates like reqwest do it already.
