fov calculating python script

Python script which reads fov from arg and calculates real horizontal and vertical fovs with it, aspect ratio and zoomfactor can also be specified.

usage:

misc/tools/fov-calc.py -h
usage: fov-calc.py [-h] fov [horizontalAspectRatio] [verticalAspectRatio] [viewzoom]

Process in-game fov cvars to horizontal and vertical degrees.

positional arguments:
  fov                   in-game fov cvar, degrees of hfov with 4:3 resolution, required field
  horizontalAspectRatio
                        Horizontal num of the aspect ratio, for 16:9 that is 16, default: 16
  verticalAspectRatio   Vertical num of the aspect ratio, for 16:9 that is 9, default: 9
  viewzoom              Zoom amount, default: 1 / no zoom

options:
  -h, --help            show this help message and exit
