Provide a simple runner which runs from a folder of images

We have runners for specific datasets, but there is no simple way right now to just run GTSFM on a folder of images.
We can solve this using the following:
- Reintroduce depricated
FolderLoader
or some version of it which just takes in a folder of input images. - Infer intrinsics from the exif file and the sensor database. If intrinsics cannot be inferred, approximate it from the image shape.
- Perform fundamental matrix estimation instead of essential matrix estimation.
Additional benchmarks needed for this task:
- F-matrix estimation for a few datasets.

@johnwlambert please add/modify information as you find useful.

Hi @ayushbaid, I was able to run the Olsson runner today with EXIF only. Other libraries like OpenMVG also require EXIF, so I think it's a reasonable assumption for now.

@johnwlambert you are right, we do not have EXIF (at least not in the standard format, we have it in other metadata. I can implement my own loader to read the EXIF in a different way.
Thanks a lot!
