libheif 1.19.7

[bigcat88]

Fixes #328

@pytest.mark.skipif(
    parse_version(pillow_heif.libheif_version()) < parse_version("1.19.7"), reason="Requires libheif 1.19.7."
)
def test_200_megapixels():
    with pytest.raises(RuntimeError):
        _ = pillow_heif.open_heif("images/heif_special/200MP.heic").data
    try:
        pillow_heif.options.DISABLE_SECURITY_LIMITS = True
        _ = pillow_heif.open_heif("images/heif_special/200MP.heic").data
    finally:
        pillow_heif.options.DISABLE_SECURITY_LIMITS = False

With latest libheif this code works.

You can now simply disable the limits and get the behavior that was in the old libhaves before "1.19" versions
