get list of dates from metadata

[m-patterson-wearable]

Is it possible to get a list of dates of data from the call to metadata? Or, at least the start / end of the study and the number of days of data?

Would be useful to automate the call to get_files when there are a large number of files and we want to get chunks of data at a time.

@m-patterson-wearable is there a specific call from here that you would like to see in actiapi?
