Symmetric quad [DRAFT]

[zsteve]

The semi-smooth Newton algorithm of [Lorenz et al. 2019] can be specialised to the case of symmetric inputs, much like the approach already used for symmetric Sinkhorn algorithm in the already implemented Sinkhorn divergence. This problem can be solved faster than the non-symmetric case.
