Release v0.1.5a

This release includes three small changes to Spirit:

• a consolidating of all document-related routes into a single file,
• the updating of copyright notices to reflect the new year,
• and the modification of the extension field regex in document validation code to better support prismjs.

Additionally, this release also includes a number of dependency updates by dependabot.
