import time is unacceptably slow

When switching from version 7.0.0 to 7.2.0, the import time grew from around 42ms to around 1.3 Seconds (31X slower)

By profiling the code running on import it seems that the issue stems from the switch from pydantic to typeguard

reproduction

pip install inflect==7.2.0
time python -c "import inflect" # results in around 1.3 seconds

pip install inflect==7.0.0
time python -c "import inflect" # results in around 0.13 seconds

python -X importtime -c "import inflect" was also useful to get the exact timing found above
