v1.1.1

Enhancements:

• Added a unique aria-label attribute to generated menu nav elements.
• Removed redundant aria-label on generated menu toggler buttons.
• Added linter configs and Github issue templates, upgraded packages, and added more information about using and contributing to this project in our CONTRIBUTING doc and new wiki.

Bug Fixes:

• Added KSES filter overrides to support the data-section-link-title data attribute on div, article, aside, and section elements, to help prevent this attribute from being wiped out by non-administrators when editing or saving posts and pages using it on versions of WordPress prior to 5.0.
