Version 0.7.3

Changes:

• actually skip request logging for docker health check
• avoid nesting error messages
• upgraded JS dependencies

Potentially breaking:

• @mapbox/geo-viewport 0.4.1 included a fix for calculating center points, which
  causes a small change in the center and zoom level automatically calculated
  here when bounds are provided for rendering. If you depend on precise
  control over how bounds are used for rendering, please check the outputs
  after upgrading.

WARNING:

This project depends on the Mapbox GL bindings for NodeJS, which are no longer maintained by Mapbox. These require
NodeJS 10, which is now beyond end of life for that version. We have no immediate path forward to upgrade to a newer version of NodeJS.
