The Python module `rpds`, a dependency of SHPC, does not get installed.

Describe the bug

When installing SHPC 0.1.30 the dependency rpds does not get installed alongside it, causing errors at runtime.

I suspect it was not included in the dependency list used by pip to install the needed packages.

shpc does not use rpds directly (and I'm not sure what it is). From the trace it looks like it's required for jsonschema, so perhaps there was an update to that library that triggered this? I think the bug report would go there, and we might just pin jsonschema to a previously working version in the meantime (while it isn't fixed).

[dipietrantonio]

Well spotted, looks like it comes from referencing. I will open an issue to that repository. Feel free to close this one, thank you!

Thanks, @dipietrantonio. We can keep this open to follow up if a pin to jsonschema is needed.
