NTRIP Server/Client and L-Band improvements

Note: If you are running firmware v3.x or greater, you can load the latest firmware or release candidate over the air. If you are using older firmware (2.x or lower) you will need to load v3.x firmware using a USB connection. We have created a Windows GUI to ease this process. Please see Updating Firmware from GUI for a step by step process.
