Adding weather to recorder/replayer

[GustavoSilvera]

Description

This change adds map weather events to the recorder to it can be reenacted just as it was recorded. This is useful to ensure the replay maintains the exact weather conditions during the recorded simulation. The implementation adds 1 event at the start of the recording to get the starting weather, then any calls to SetWeather (See Weather/Weather.cpp) with changed params will be added to the recorder as a one-time event.

I've tested recording, replaying, and querying. All work as expected.

Example line in the recorder query:

Weather events: 1
  Cloudiness: 61.76, Precipitation: 21.76, PrecipitationDeposits: 11.76, WindIntensity: 40.00, SunAzimuthAngle: 313.80, SunAltitudeAngle: 9.92, FogDensity: 11.76, FogDistance: 0.75, FogFalloff: 0.10, Wetness: 100.00, ScatteringIntensity: 1.00, MieScatteringScale: 0.03, RayleighScatteringScale: 0.03, 

Where has this been tested?

• Platform(s): Linux (Ubuntu 20.04), Windows 10
• Python version(s): 3.8 on Conda
• Unreal Engine version(s): 4.26 (CarlaUnreal)

Thanks for the PR.
We are working in making the recorder more deterministic (exact position of clouds and foliage animation,...), so we will check your changes to merge them.

Sounds good, hope it can be useful!
