use tabsets to define different views within the sactuaries

[7yl4r]

Some views will be of more interest to some sanctuaries more than others. examples:

• FGB care a lot about bleaching, but Stellwagon doesn't

My proposed solution for this is to have different views for different goals displayed as a tab.
Ideas for tabs:

• default view
• coral bleaching. See this issue comment for example plots
• algae bloom
• forecast model & data details
