Component Apps: Add support for GeoJSON features

[shawncrawley]

Description

I received feedback from someone trying to learn Component Apps that they were not able to display GeoJSON on their map. Turns out that this was a shortcoming of Comopnent Apps that has now been addressed with this PR. A new Recipe was added to document how this is now done.

Changes Made to Code

• tethys_components/resources/reactjs_module_wrapper_template.js was updated to more robustly handle events
• tethys_apps/static/tethys_apps/js/ol-mods.js was added to handle unique GeoJSON cases
• tethys_components/library.py was updated to included an OVERRIDES variable that can override built-in library components with a custom component. In this case, the lib.ol.source.Vector component is overridden with the custom lib.olmod.VectorSource package that points to "tethys_apps/static/tethys_apps/js/ol-mods.js"
