Support SAM2

[andr-ec]

Would be awesome to support sam2!

https://ai.meta.com/sam2/

There's an implementation of the original sam:

https://elixirforum.com/t/running-facebooks-segmentation-model-using-ortex/63422/13

It also ortex.

Hi! Thank You for reaching out! Right now there is no memory bank export in onnx for the SAM2 model (it is said to be exported 'soon'), so the functionality would be the same as in SAM (video tracking would not work). We are not plannig on doing the export on our own at this time, but this might change in the future

It looks like someone has now done it?
Is that all that's needed?
