Update pdfminer_utils.py

[Nathan-GoSupply]

Fix for 'PSSyntaxError' import error:
"cannot import name 'PSSyntaxError' from 'pdfminer.pdfparser'"

Latest pdfminer-six doesn't import PSSyntaxError into pdfminer.pdfparser anymore. It must now be directly imported from its source (pdfminer.psexceptions)

Thanks for the patch. However, I think the version of pdfminer should be checked to determine whether to import the older or newer version for backwards compat.

[Nathan-GoSupply]

This change will also work on the older version. In the older version, pdfminer.pdfparser imports PSSyntaxError from pdfminer.psexceptions.

However they have since removed the PSSyntaxError import from pdfminer.pdfparser.

Therefore, for the new pdfminer version we must change to directly import from pdfminer.psexceptions.
So instead of
pdfminer_utils.py -> pdfminer.pdfparser ->pdfminer.psexceptions

We can do
pdfminer_utils.py -> pdfminer.psexceptions

PSSyntaxError is defined in pdfminer.psexceptions in both the old and new versions of pdfminer, so we will still get backward compatibility.

Here is the commit for the change on pdfminer.

please add a bullet under Fixes in, CHANGELOG.md.

thanks for the contribution @Nathan-GoSupply ! the reference to the pdfminer commit is also appreciated.
