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>

Change log

• nerfcapture.bash
  Changes support SpectacularAI input and output the dataset already processed with SplaTAM.
• nerfcapture2dataset.py
  Changes make it possible to load a local NeRFCapture dataset and make it compatible with the SplaTAM expected input.
• final_recon.py & splatam.py
  Override config file parameters with the command line arguments.
• RESULTS.md
  Explored technologies and obtained results overview.
• README.md
  Run instructions for other Ekumembers.

First pass. Are there any datasets to play with this?

[Santoi]

Thanks for your review, @hidmic ! Ready for second pass.

Added a dataset in datasets/hq-pool-table-spec.

@Santoi this hangs the GitHub UI for PR reviews. Does the dataset need to live here? Can we put it elsewhere and instruct the user to request access?

On an unrelated note, I see references to Frodo in the repository. This is a public repository. Results are not particularly sensitive but I'd suggest removing company terminology.

[Santoi]

Can we put it elsewhere and instruct the user to request access?

@hidmic Sure. Does it make sense to add a README in the datasets directory with those instructions? Additionally I was thinking of adding a file with the URL to request access to.

[hidmic]

@Santoi a README.md under datasets sounds good. A GDrive URL, on the other hand, is a bit too much IMO. I'd just instruct folks to send an email to research@ekumenlabs.com for the datasets. We can vet them there.

If it helps, use an LLM to adjust the writing (punctuation, tenses, overall cohesion).

Also, link to app store would be nice.

@Santoi nit: links to product briefs would be nice.

Suggested change

	Requires the host to be connected into the recording device, so as to process the input while it is being captured.

Suggested change

	Offline mode is currently bugged. There is an issue with the recording processing, which is not converting the depth buffer correctly into 16 bit numbers. See [this author comment](https://github.com/jc211/NeRFCapture/issues/10#issuecomment-1888164311) for more details.
