Zoom in (or out) on demand.
Adds a key bind to override the main field of view (fov).
Inspired by essentially the same feature from Red Orchestra 2.
The configuration must be changed to set the secondary fov and the key bind to activate it.
The recommended way to change the configuration is via the BepInEx Configuration Manager. It is especially helpful with key binds.
Alternatively the config files can be edited manually under <game-directory>/BepInEx/config/SmilingLizard.plugins.SecondFOV.cfg.
