This is WIP on the car racing environment from the OG gym library. The car track is done and tested.

Added a new environment - LEM Lander - which is the classic Atari LEM simulator that takes a burn rate and a burn time as input and calculates the landing parameters for a direct descent LEM. The GUI for the env needs some text to identify the 3 gauges (Fuel, Altitude, Speed). The ImageSharp library has a font library but it might need licensing that is not compatible with GYM.Net.

I also added a frame rate control to the render method for the LEM environment to slow it down and force the display of the GUI.

Code is not documented well, working on that next.

Sorry, something went wrong.

Uh oh!

Almost ready. The track draws and there is a random driver test that seems to move the track properly. Can't see the car and I still need to draw the indicators.
