Move encoders weights to HF-Hub

[qubvel]

Fixes:

• URLError when loading pretrained weights. #144
• SSL: CERTIFICATE_VERIFY_FAILED #216
• SSL error when trying to load ImageNet weights for se_resnext101_32x4d encoder with any backbone. #653
• UNet model : pretrained InceptionV4 encoder not available #675
• Certificate has expired. Endoncer: inceptionresnetv2 #743
• Expired SSL certificate #745
• SSL certificate has expired error when using a pretrained model #797
• SSL certificate expired for se_resnext50_32x4d encoder #841
• SSL: CERTIFICATE_VERIFY_FAILED error  #875

OMG there were a lot of issues

Very happy about how many issues this closes (and will prevent in the future)

Reviewed the obvious things, probably safe to merge if we've confirmed that all downloads work with the new URLs.

Yeah, I've already run locally download for all encoders
