respx fails to build with Python 3.10

[fabaff]

There is a build failure with Python 3.10:

TypeError: traceback_exception_init() got an unexpected keyword argument 'compact'

For the full details please check https://bugzilla.redhat.com/show_bug.cgi?id=1927699

Thanks

Thanks for reporting. Gave a quick look, and the stack trace smells tests 3:rd party issue, i.e. trio (?).

I marked the TrioBackend test case to be skipped on 3.10 for now, seems to solve this issue.

@fabaff please verify, and I'll merge #137.

trio has an issue on this : python-trio/trio#1899

Hello, I can confirm respx builds with Python3.10 with this patch until trio is fixed. Thank you.
