email date format flexibility (#4072)
we are seeing some .eml files come through the VLM partitioner. Which
then downgrades to hi-res i believe.
For some reason they have a date format that is not standard email
format. But it is still legitimate.
This uses a more robust date package to parse the date. This package is
already installed.
