Adding support for SIFT

[demplo]

Hello @fabio-sim , thanks for the amazing work!
Is it feasible to have SIFT working with the ONNX model? Are you planning to add the possibility to run LightGlue+SIFT?

Hi @demplo, thank you for your interest in LightGlue-ONNX.

Not at the moment, but a PR would be welcome :)

hi, fabio, I have implemented ONNX support for sift-lightglue and have pushed it to LightGlue ONNX, but I am not very familiar with using GitHub. If you have any questions, please feel free to contact me
