Add more data to error message

[Yay295]

This changes the error message from
offset is neither short nor long
to
offset is neither short nor long: Tag ID 273 Field Type 16 Field Size 8 Count 1

Could you give an example of how to trigger this error?

[Yay295]

With #8317, test_bigtiff() in test_file_tiff.py triggers this error if del im.tag_v2[273] is removed from the test.

Would it not be more consistent with the rest of TiffImagePlugin to log the extra information instead?

Pillow/src/PIL/TiffImagePlugin.py

Lines 1429 to 1435 in eeb3d04

	if samples_per_pixel > MAX_SAMPLESPERPIXEL:
	# DOS check, samples_per_pixel can be a Long, and we extend the tuple below
	logger.error(
	"More samples per pixel than can be decoded: %s", samples_per_pixel
	)
	msg = "Invalid value for samples per pixel"
	raise SyntaxError(msg)

It might. Logging is only used in five files in Pillow though (Image, PcxImagePlugin, PngImagePlugin, TiffImagePlugin, helper).

With #8317, test_bigtiff() in test_file_tiff.py triggers this error if del im.tag_v2[273] is removed from the test.

Just a note: this specific example stopped triggering the error after #8417 added support for LONG8.

I've created #8568 as an alternative to this, using my suggestion of logging.

#8568 has been merged instead.
