Support event filters in calendar component

[maxatdetroit]

Part of #182

See context in #182.

In this stack of PRs, we'll:

1. (Done) Introduce a new calendar component that accepts a static list of events
2. (This PR) Extend the component to accept a list of filter controls, starting with a radio control that will filter events by an arbitrary 'category' field and value.
3. Support custom colors that will control the color of events on the calendar and event filters

This PR

• Update cod-calendar component to support passing a list of event filters to the event-filters attribute
• Update storybook with an example of filters
• Update height of calendar to be responsive (allows height to grow on mobile when width is compressed)

Testing

See storybook in chromatic and test various number of filters and scenarios (e.g. filter down to no events, go next and prev months after filter, etc.)
