Support for standardized output format

[yarikoptic]

Hi dannce folks,

An interesting project! I was referred to it by @HollyMooreNIH during EMBER archive "support zoom". If I got it right, ATM output of dannce is a MATLAB file with some (did not yet find) data model. I wondered how it could potentially relate, or be converted to/from, to the model of other tools and standards (NWB, BIDS).

Here is relevant recent discussion between developers of relevant efforts:

• Motion trajectories & pose extracted data for animal beh research bids-standard/bids-specification#2057

I hope that dannce output format could also be conveniently standardized. I wondered if it is anyhow compatible with ndx-pose model and/or BIDS motion: https://bids-specification.readthedocs.io/en/stable/modality-specific-files/motion.html

"Pay-ahead-ment" for your efforts:

• Add codespell support (config, workflow to detect/not fix) and make it fix few typos #158

Thanks in advance!
