MeasureTheory.measure_preimage_mul

∀ {G : Type u_1} [inst : MeasurableSpace G] [inst_1 : Group G] [MeasurableMul G] (μ : MeasureTheory.Measure G)
  [μ.IsMulLeftInvariant] (g : G) (A : Set G), μ ((fun h => g * h) ⁻¹' A) = μ A

We shorten this from measure_preimage_mul_left, since left invariant is the preferred option for measures in this formalization.
