Description of feature request

Create a new Chat component that displays an ongoing chat with one or more people

Expected behavior

• Display chat messages (array of items input as prop)
• Specify which ones are the user themselves and style those different than messages from other people
• Include certain metadata for each message like name and date
• Date should be formatted to use the user's browser timezone (check utility functions for that, might already have something to help)
• Input box for writing a new message
• Props for what happens when you send a message
• Prop for limit to new message size
• Prop for loading and correct loading indicators using that
• Good layout and scrolling behavior
• Mobile friendly and responsive
• Use utility classnames from finallyreact (don't use inline styles or tailwind or anything like that)
• No external libraries allowed at all (except React)
• Should be accessible: aria labels, semantics, color contrast, keyboard navigation, tab index, etc.
• Use existing components from FinallyReact when applicable
