be482ea097 Advanced Ballistics - Drag model revamp & Spin drift correction (#5566)
* Advanced Ballistics - Drag model revamp
- Moved away from using the drag tables from the GNU exterior ballistics library
- The drag functions are now based off this data from JBM Ballistics: http://www.jbmballistics.com/ballistics/downloads/text/
- The differences are minor, but some players might still appreciate the additional authenticity

* The Mach number is now calculated in relation to the air temperature.

* Improved speed of sound calculation accuracy.

* Advanced Ballistics - DLL update

* Advanced Ballistics - Added drag function reference (JBM Ballistics)

* Advanced Ballistics - Fixed calculation error in the spin drift simulation
- The error was introduced with this PR (https://github.com/acemod/ACE3/pull/4708)

* More descriptive variable names

* Minor performance optimizations

* Fixed some minor issues

* DLL rebuild

* Utilize new 'toFixed' script command
- Small performance improvement

* Fixed a typo

* Use correct reference speed for the drag compensation

* Updated all 'airFriction' values to match the new drag model

* 'Default' atmosphere now equals the ICAO standard atmosphere

* Update reference humidity to meet the ICAO standard
