Add light datasets for demos and tests to djarchive

[kabilar]

Demo datasets

• Only needs to include one acquisition package and one analysis package.
• It would be ideal for data to be <1 GB.
• workflow-array-ephys
• workflow-calcium-imaging
• workflow-miniscope
• workflow-deeplabcut
• workflow-facemap

Test datasets

• Should be more comprehensive including all acquisition and analysis packages that are supported.
• workflow-array-ephys
• workflow-calcium-imaging
• workflow-miniscope
• workflow-deeplabcut
• workflow-facemap

• Demo:
  • We had a volunteer who was willing to record demo ephys data for us. Did they follow through?
  • I have a potential lead on calcium imaging data.
• Test:
  • I'm under the impression that we already have solid tests data sets for calcium imaging and ephys, no?
  • The demo data set for DLC will work for all currently supported features
