Fix duration format overflow handling

[wanxiankai]

Fixes #1511.

Summary

• catch decimal parsing exceptions raised by isoduration while checking the duration format
• add a regression test for large exponent duration strings so they become format validation errors instead of uncaught decimal.Overflow exceptions

• .venv/bin/python -m unittest jsonschema.tests.test_format.TestFormatChecker.test_duration_overflow_is_invalid
• .venv/bin/python -m unittest jsonschema.tests.test_format
