caltechlibrary/handprint: Release 1.0.0

This is the first sufficiently complete and robust version of Handprint that can finally be called a version 1.0. There are very many changes compared to version 0.10.0, including a new way to provide credential files, new default output (in which results from different services are placed side-by-side in a single large image), new command-line arguments, parallel execution, and more.

The file CHANGES contains a more complete change log that includes information about previous releases.
