Right Homology of short complexes

In this file, we define the dual notions to those defined in Algebra.Homology.ShortComplex.LeftHomology. In particular, if S : ShortComplex C is a short complex consisting of two composable maps f : X₁ ⟶ X₂ and g : X₂ ⟶ X₃ such that f ≫ g = 0, we define h : S.RightHomologyData to be the datum of morphisms p : X₂ ⟶ Q and ι : H ⟶ Q such that Q identifies to the cokernel of f and H to the kernel of the induced map g' : Q ⟶ X₃.

When such a S.RightHomologyData exists, we shall say that [S.HasRightHomology] and we define S.rightHomology to be the H field of a chosen right homology data. Similarly, we define S.opcycles to be the Q field.

In Homology.lean, when S has two compatible left and right homology data (i.e. they give the same H up to a canonical isomorphism), we shall define [S.HasHomology] and S.homology.

If φ : S₁ ⟶ S₂ is a morphism of short complexes such that φ.τ₁ is epi, φ.τ₂ is an iso and φ.τ₃ is mono, then a right homology data for S₂ induces a right homology data for S₁ with the same Q and H fields. This is obtained by dualising LeftHomologyData.ofEpiOfIsIsoOfMono. The inverse construction is ofEpiOfIsIsoOfMono.
