Created an Acceleration map. Very simple map with no decorations.

- Required creation of small orange cone assets including small orange cone splines.
- Created a finish line which stops the time of the startfinish line.
- Known Bug: All orange cones are being printed as large Orange

Added Skidpad track with no decorations. Track is based on EUFS Implementation found here: https://gitlab.com/eufs/eufs_sim/-/blob/ros2/eufs_gazebo/tracks

Required multiple splines so edited refereeBP.uasset to print out all the splines required. It should not break when doing other tracks and those references do not exist due to the ifvalid check. If there is a better way of doing it, that should be done!

Some fixes to acceleration with better cone distances  (5m)

Bug that all small orange cones are printed to ros as big orange still exists.

My changes for the referee to incorporate accel and skidpad tracks broke some references in the existing tracks. Cones were not being output to ros. Updated them so that the blue/yelow cones and start/finish line cones on all maps are now being output.

Started the documentation for map building tutorial. Please correct me if any information is wrong! Or make edits if more information should be included!

I do not know how to change the weather or daytime cycles so that section needs to be updated.

- Added AppendSmallOrangeCone to Airsim plugin so that cones are now properly being output to ros.
- Fixed the refereeebp to reflect above.

Added some fence/wall decoration and timers on the walls.
