Remove unneeded code for handling zero-width characters

[radarhere]

Pillow/src/PIL/BdfFontFile.py

Lines 85 to 89 in 1cdb9a4

	try:
	im = Image.frombytes("1", (width, height), bitmap, "hex", "1")
	except ValueError:
	# deal with zero-width characters
	im = Image.new("1", (width, height))

I don't think the exception handling is needed here.

It has been present since PIL. A test was added in #8783, but it was an artificial scenario to improve coverage, not a real need.

'deal with zero-width characters' would make you think that it would be needed for

Image.frombytes("1", (0, 0), b"", "hex", "1")
Image.frombytes("1", (0, 1), b"", "hex", "1")

but those lines don't raise an error.
