Function hydra_dx_math::ema::volume_weighted_average

pub fn volume_weighted_average(
    prev: EmaVolume,
    incoming: EmaVolume,
    weight: Fraction
) -> EmaVolume

Calculate a weighted average for the givenEmaVolumes. prev is the previous oracle value, incoming is the new value to integrate. weight is how much weight to give the new value.

Note: Just delegates to balance_weighted_average under the hood. Note: Rounding is biased towards prev.
