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)

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