Online tracking

[DSliwowski1]

First of all, thanks for the great work!

In my use case, the videos often have 12k-15k frames, and it is not possible for me to load the full video into the VRAM of my GPU as you do in the current version of the code. I was wondering if it is possible to do online tracking like in Co-tracker. I've checked the code but did not see anything related to this, but I'm asking in case I missed something. Perhaps, with some modifications online tracking would be possible. In that case, could you point me to the most important places that would have to be modified?

Best,
Daniel
