Files are overwritten on the second pass

[gauvinalexandre]

When running bidskit for the second time using the following command,

bidskit -d {data_dir} -subj {subjects_to_convert} -sess {sessions_to_convert}

the file participants.json and dataset_description.json are overwritten, even if I've set them myself. Then, bids-validator obviously complains as the columns of the participants.tsv are not described and dataset_description.json containing empty fields...

Should'nt bidskit detect if pre-existing files exist before overwriting them?

Good catch and yes, bidskit shouldn't be overwriting user edited files like these top-level JSONs. Working on a fix now.
