Feature request: Add support for ESP32 long range mode

[drtrigon]

ESP32 supports a long-range mode with ~1km line of sight range. This mode was introduced quite a while ago.

Please include an option to enable this mode when using ESP32.

ESP32 lacks an appropriate high-speed interface for a video stream.

@seeul8er: What is the relation between long-range mode and "high-speed interface for video stream" ? I would like to use DroneBridge for Telemetry with ArduPilot. That does not need to be high-speed. As I understand from the linked page it should be fairly easy to enable the long-range mode and thus I consider it as useful.
