Dockerize the project for nicer demo experience

Maybe a cool addition to the project. If you have any suggestions to fix anything please do comment:)

I think this would be good addition to the project.

Before noticing this PR, I already started doing my own non-conda version (https://github.com/jonppe/dust3r/commit/5089d1dcb867efd8556d4285a5eacc3a82c4bf41) but this was still helpful to find all the necessary apt packages. In fact there seems to be also another PR to add Dockerfile: https://github.com/naver/dust3r/pull/5

The non-conda installation feels somehow slightly more clean but I guess there's not much difference.

I can try and integrate the venv version no problemo:) it looks cleaner yeah:) Thanks for pointing out!

The image downloaded in the Dockerfile mentioned in pr #5 is kinda large (10GB) nvidia containers list. But lets use it as it has nvidia kernel options available (other image did not have them) and croco model can be successfully installed now.

Now it is cleaned up thanks @jonppe <3 !
