Add support for local datasets.

[Santoi]

Motivation

This PR provides the means to run SplaTAM on previously recorded datasets with the Spectacular AI tool using an iPhone Pro 14 or higher (basically, with a depth sensor).

Description

Original SplaTAM scripts have been adapted so the config files don't have to be manually edited.
The bash script entry point now takes the usual config file, and additionally the path to the dataset previously recorded with SpectacularAI.

bash bash_scripts/nerfcapture.bash configs/iphone/nerfcapture.py <spectacularAI_dataset_location>
