Add support for passing a dict (cam_name -> files) into fit_eks_multicam

[darsnack]

This adds support to fit_eks_multicam for passing a mapping from camera name to a list of CSV files. Useful for users accessing through the API who might have naming conventions that do not fit the simple logic for detecting files per view currently used.

Indirectly, it enforces that the keys of the mapping passed in match either camera_names or the calibration .toml (otherwise the valid files will be length 0).
