Add GIM LightGlue weights

[Phil26AT]

Simple download script to download the weights of GIM: Learning Generalizable Image Matcher From Internet Videos by Xuelun Shen (@xuelunshen) et al. to LightGlue.

They are directly compatible with LightGlue and SuperPoint features:

from lightglue import LightGlue, SuperPoint

# SuperPoint+LightGlue
extractor = SuperPoint(max_num_keypoints=2048).eval().cuda()  # load the extractor
matcher = LightGlue(features='gim_superpoint').eval().cuda()  # load the matcher
