Bounds Search

[bbovenzi]

• Add optional max/min Lat and Lng bounds to organization search. If there are bounds we will search by that, otherwise we will fall back on a center lat, lng with a distance radius
• "Search this area" will search by bounds
• Change default centers, radius, and zoom for each org to make sure our default view is centered where we have data, at a useful zoom level, and a large enough radius to fill the whole map on desktop
• Refactor how the map center "origin" is calculated. (combine and remove redundant variables, rename some variables, remove unnecessary sessionStorage variables)
• Add a button to the search bar to search your current location (if we have it, otherwise its disabled)
