Fix missing channels in OpenEphys XML

[weiglszonja]

This PR introduces a standalone script (fix_openephys_xml_missing_channels.py) that:

• Issues a warning when missing channels are detected in the XML (based on the CHANNELS tag)
• Fills in missing channels in the CHANNELS, ELECTRODE_XPOS, and ELECTRODE_YPOS tags using inferred values
• Optionally overwrites the original XML or saves a corrected copy (.fixed.xml).

@h-mayorquin @alejoe91 let me know what you think

Hi Szonja.
Ok for me.
Would it be possible to add a bit more context doc in the docstring of the function to explain the kind of bugs expected and maybe which version could be affected ?

Thanks, I agree. I'll add this.
