Added the RTMA and SREF data sources. These are both high-resolution, short-term forecasting models covering North America, and provide significant improvements to our 24-hour forecasts in the region. Additionally, these models make the LAMP data source redundant, and so it has been removed.

Additionally, we added a header to API responses, X-Forecast-API-Calls, which contains how many API requests have been made so far on the current day. This is helpful for tracking your API usage in an automated fashion.

As always, please see our documentation for details.
