Subject: [PATCH] refactor: Add strong typing to document creation (#2161)

## Relevant issue(s)

Resolves #935
Resolves #1703

## Description

This PR adds strong document typing to document creation by using the
field descriptions to determine Go types. Datetime is now properly
supported and formatting is enforced.

Note that a lot of docIDs have changed as a result of this refactor.
