Caltechdata-api

This release fixes a bug in caltechdata_edit, which impacted records without external files.

This release includes a bug fix for community record submissions.

This release adds new options to caltechdata_api:

- default_preview is the file that will show up in the CaltechDATA file preview pane
- file_descriptions is an array of text that is associated with external file links
- s3_link is the parent download link for external file links (listed at the top of the external files block)

This release fixes a bug with duplicate filenames, supports passing embargo settings, and allows users to provide custom 'updated' dates. The new custom external files description type is also supported.

`get_files` is fixed to work with the current version of CaltechDATA.

An example automated data transfer script `process_tomograms.py` is included.
