Have the abillity to change auto_balance direction choice threshold

[qleguennec]

Hello, thanks for the app, exactly what I was looking for.

I'd like to be able to change the threshold at which yabai chooses to change the default direction of the split.

Example, let the threshold be 0.3, opening a new window would only change the default direction if the currently focused window's new size would be lower than a third of its current size. Currently the direction change happens for sizes < 0.5 * current_size.

Is that possible and/or difficult to implement?

Thanks.
