In mvisalli/shipr: ships for whales functions

Location

• from: github.com/schloerke/leaflet-providers@urlProtocol

• Inspiration taken from https://github.com/leaflet-extras/leaflet-providers/commit/dea786a3219f9cc824b8e96903a17f46ca9a5afc to use the 'old' relative url protocols and to 'upgrade' them at js runtime.

Notes...

• Copy/paste provider information into providers.json

var providers = L.TileLayer.Provider.providers;
JSON.stringify(providers, null, "  ");

• ./data-raw/providerNames.R was re-ran to update to the latest providers

• Some providers had their protocols turned into '//'.

• This allows browsers to pick the protocol
• To stop files from the protocols staying as files, a ducktape patch was applied to L.TileLayer.prototype.initialize and L.TileLayer.WMS.prototype.initialize
