MLSO KCor data files can't be ingested

[dgarciabriseno]

This will be more important when KCor comes back online.

They provided some data in 2024, but the XML data is malformed and can't be processed as valid XML.
We can likely add a patch to work around this, but since there's no new data coming in, it's not much of a priority.

Error reported by glymur (used by sunpy to read jp2 files) when trying to parse the XML:

/usr/local/lib/python3.12/dist-packages/glymur/jp2box.py:3084: UserWarning: XMLSyntaxError encountered while parsing an XML box at byte offset 77:

        "error parsing attribute name, line 12, column 7 (<string>, line 12)"

Further debug shows the root cause seems to be these dollar signs in the XML tag:
MJD_D$...

  1 <?xml version="1.0" encoding="UTF-8"?>
  2 <meta>
  3 <fits>
  4 <SIMPLE>1</SIMPLE>
  5 <BITPIX>-32</BITPIX>
  6 <NAXIS>2</NAXIS>
  7 <NAXIS1>1024</NAXIS1>
  8 <NAXIS2>1024</NAXIS2>
  9 <EXTEND>0</EXTEND>
 10 <DATE-OBS>2024-04-09T17:48:52</DATE-OBS>
 11 <DATE-END>2024-04-09T17:49:07</DATE-END>
 12 <MJD_D$OBS>60409.742</MJD_D$OBS>
 13 <MJD_D$END>60409.742</MJD_D$END>

This MJD tag wasn't in earlier files from 2022 and earlier.

I sent an email to their contact address letting them know they have bad XML in these headers.
