Handle rational tags with a zero denominator

[radarhere]

Resolves #8471

When adding type hints in #8270, I added a cast to float.

Pillow/src/PIL/TiffImagePlugin.py

Lines 294 to 297 in 11c654c

	def _limit_rational(
	val: float | Fraction | IFDRational, max_val: int
	) -> tuple[IntegralLike, IntegralLike]:
	inv = abs(float(val)) > 1

However, that is causing a ZeroDivisionError when the value is an IFDRational with a denominator of zero.

I'm able to remove the cast without causing a mypy error, so I've reverted that specific change.

I created a test image with

im = Image.new("1", (1, 1))
exif = im.getexif()
exif[34853] = {
    2: (IFDRational(0, 0), IFDRational(0, 0), IFDRational(0, 0))
}
im.save("gpsinfo_zero_latitude.jpg", exif=exif)

After fixing the type hint errors in #8474, the ZeroDivisionError starts occurring there.

So that PR can replace this one.
