This allows for use cases like compression where the codec may compress multiple payloads into one.

What was changed
Support
{namespace}templating in endpoint URL and send X-Namespace header. Don't assume that the payload count returned from the codec server will match what we sent.Why?
This allows for URL separation of encoders for different namespaces as encouraged by our sample code server. This is inline with the tctl support in temporalio/tctl#161.
Also no longer assume that payload count will be consistent before/after decoding as some codecs may benefit from mapping multiple payloads into one (for example, better compression ratios).
Checklist
Tested against the remote codec server in samples-go.
