pycrdt throws PanicException in some cases which is unhandled

[acnebs]

Description

Sometimes when calling ydoc.get_update(encoded_update) from pycrdt, a PanicException is thrown which I try to handle from userland but somehow seems to escape my try...except block.

You can read more about this exception from pyo3 in this GH issue: PyO3/pyo3#3519

Specifically, the PanicException that is thrown for me when calling ydoc.get_update(encoded_update) has this exception message:

called Result::unwrap() on an Err value: VarIntSizeExceeded(70)

Reproduce

Struggling to consistently reproduce, am unsure what exact binary payloads are causing the panic.

Expected behavior

No panics, or at least PanicExceptions I can catch.
