Running several wasm modules but exposing a single pprof endpoint

[alban]

I have a Go application (inspektor-gadget/inspektor-gadget#3992) that can potentially run several independent WASM modules with wazero. I am trying to use wzprof to expose pprof on a single TCP port, but it does not seem supported:

• wzprof.Handler() is instantiated for a specific Profiling instance. I cannot call wzprof.ProfilingFor multiple times for a single http handler.
• wzprof.Handler() cannot use a different path than "/debug/pprof/" because the handler would fail on pprof.go#L146 (strings.CutPrefix), so I cannot use several http handlers on separate URLs for different WASM modules.

At the moment, I listen on a different TCP port for each WASM module. Is it possible to use wzprof.Handler() in a different way to avoid using different TCP ports?
