Air config tweak

[snoodledev]

Describe the feature you have in mind.

For the "Air" config options, I feel that having one value for air usage when stationary, and one value for air usage when moving around in the air, would be more versatile for balancing than the current two options.
Alternatively, a third config option that controls air usage while stationary would achieve the same result.

Thanks for your work, this is a lovely little mod that fits in very well with Create :)

Does this solve a particular problem?

Currently, there isn't much of a difference between Hover and non-Hover modes in terms of movement capability. Being able to limit travel distance while allowing stationary hovering for longer amounts of time would be a very useful option for balancing the jetpack with other movement options in a modpack.
