Apologies for the nuissance!! This change is part of a final review
of names before the release of v1 final.
Motivations:
- "xfn" is a lot shorter than "middleware", making it more
convenient to use at signal calls, compare:
(log! {:middleware my-fn} "msg")
(log! {:xfn my-fn} "msg"}
- "middleware" was originally chosen to match Timbre's terminology,
but actually carries some misleading connotations that in hindsight
are probably better avoided while we still have the chance to change
this.
Thanks to @AdamFrey for reporting this issue!

Previously:
Attempting to run AOT'd code using Telemere would result in errors like:
"Attempting to call unbound fn: #'taoensso.telemere.handlers.open-telemetry/handler:open-telemetry-logger"
The approach I was using of conditionally requiring namespaces and then aliasing vars seems to be inherently
fragile under AOT, and was leading to the remote source var being unbound.
With this commit I've now switched to a simpler approach - where we conditionally require namespaces *without*
the need for any aliasing.
