I am trying to upgrade to sttp client 4, but can’t figure out how to manage SttpClientInterprer.  
I am on 1.11.9 (which I think is the latest now), but `SttpClientInterpreter().toSecureRequest(...)`  
returns ` A => I => client3.Request[DecodeResult[Either[E, O]], R]`  
What is a good way to get client4 instead?

As we’re still finishing up the design of sttp4 (it’s taking a long time, I know - and sorry - but we are resource-constrainted), we didn’t yet create an sttp4 client module for tapir. So you’ll need to write your own (copying most of the funcitonality for the sttp3 version), or wait a bit longer for us to bring sttp-client4 to an RC stage, at which point we’ll also introduce a tapir module.
