Bug report

[ChenShuwei1001]

A bug hard to notice:
in 'basicsr/models/crop_validation.py', the beginning of method 'forward_crop', two assert statements are used:
assert lq_size == 64 or 48, "Default patch size of LR images during training and validation should be {}.".format(lq_size)
assert overlap == 16 or 12, "Default overlap of patches during validation should be {}.".format(overlap)
you should insteadly use
assert lq_size == 64 or lq_size ==48, "Default patch size of LR images during training and validation should be {}.".format(lq_size)
assert overlap == 16 or lq_size ==12, "Default overlap of patches during validation should be {}.".format(overlap)
because origin statement will be explained as assert (lq_size==64) or (48), which is always True
