Locally Low-Rank operator
I would like to use the LLR operator, and am considering making a PR.

Thank you @baggepinnen, I’m assuming this is in the context of IndBallRank or NuclearNorm or both?
I was thinking about composing it with NuclearNorm, but if the implementation could be generic with respect to the choice of inner prox, IndBallRank or NuclearNorm.
