ponyorm: FTBFS on Python 3.10

[Brian Murray]

Imported from Debian bug http://bugs.debian.org/1000716:

Package: python3-pony
Version: 0.7.14-1
Severity: serious
User: <email address hidden>
Usertags: python3.10

Hello,

It seems the current version of ponyorm is broken on python3.10. If you
look closely at the logs from the latest DebCI run [1], it outputs
(without failing........):

> Sorry, but pony 0.7.14 requires Python of one of the following
> versions: 2.7, 3.3-3.9. You have version 3.10.0+

Actually running pony on 3.10 outputs something like:

ERROR: tests (unittest.loader._FailedTest)

ImportError: Failed to import test module: tests

    import parser
ModuleNotFoundError: No module named 'parser'

This is because the parser module has been removed in Python 3.10 in
favor of ast [2].

I'll suggest upstream to fail their testsuite when ran on Python 3.10.
