A live component that renders a map using AWS Location Service.

You must pass in the following assigns:

• :api_key - The AWS Location Service API key.
• :map_name - The name of the map to render.
• :region - The AWS region where the map is located.

You can optionally pass in the following assigns:

• :class - The CSS classes to apply to the map container. You'll most likely want to set the height and width of the map here.
• :click_handler - A boolean indicating whether to handle map clicks.

If :click_handler is true, the component will send a map-clicked event to the parent live view when the map is clicked.
