climpred.classes.HindcastEnsemble.bootstrap dim member and init simultaneously

[zmli-666]

Could the HindcastEnsemble.bootstrapresample for "member" and "init" in dim simultaneously? And how?

Thank you for considering climpred and raising this issue @zmli-666.

Bootstrapping / resampling along both dimensions simultaneously isn't implemented (yet). It could be implemented by doing first the init resampling and then internally a member resampling on top of that.

PR welcome 😃
