Residual that penalizes the difference between between(a, b) and a_T_b.

In vector space terms that would be: (b - a) - a_T_b

In lie group terms: local_coordinates(a_T_b, between(a, b)) to_tangent(compose(inverse(a_T_b), compose(inverse(a), b)))

Args: sqrt_info: Square root information matrix to whiten residual. This can be computed from a covariance matrix as the cholesky decomposition of the inverse. In the case of a diagonal it will contain 1/sigma values. Must match the tangent dim. jacobian: (6x12) jacobian of res wrt args a (6), b (6) hessian: (12x12) Gauss-Newton hessian for args a (6), b (6) rhs: (12x1) Gauss-Newton rhs for args a (6), b (6)
