An AffineTransform helper, similar to the implementation in MLIR/xDSL.
However, the representation is handled by a matrix A and B instead of the AffineExpr tree, which should make things much easier. I plan to use this class inside the
compiler/ir/stream/access_pattern.pyutility classes.This also gets rid of the canonicalization problem for affine transforms.
