[feature] A11y label

[sawyerclick]

Describe the feature
Add an ability for users to label the slider via aria-label, aria-labelledby, aria-describedby. An accessible name is required for this to be a true replacement for <input type='range'/>.

Explain it's value / reasoning
Simple in-line labeling with minimal refactor. This creates an explicit label opposed to any implicit association by wrapping the text or otherwise

Additional context
See labelling section on MDN: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/slider_role#the_slider_role_compared_other_range_options
