Anonymization failure cites BytesIO object instead of input filename

[blairconrad]

Anonymizing a Deflated Explicit VR Little Endian (1.2.840.10008.1.2.1.99) file results in dicognito erroring out with

Error occurred while converting <_io.BytesIO object at 0x0000022DD4CEA160>. Aborting.
Traceback (most recent call last):
  File "E:\Dev\dicognito\.venv\dicognito\Lib\site-packages\pydicom\tag.py", line 28, in tag_in_exception

The "<_io.BytesIO object at 0x0000022DD4CEA160>" should be the input filename.

Occurs whether using --output-directory or --in-place.

Caused by pydicom/pydicom#1937. The dataset's filename attribute is replaced with a BytesIO.
