After discussion with @rflamary we decided to expand the PR with additional features, namely two barycenter solvers: - a solver for the iterates of H of [76](https://arxiv.org/abs/2501.04016) with an optional...

After some updates to the paper behind these algorithms (the paper update is soon to come), I implemented another barycenter solver which corresponds exactly to the method studied theoretically [in...
