Add support for running batch on a single lightcurve

[wilsonbb]

Change Description

In #409 it was proposed to add a batch helper function try_batch which would allow Ensemble.batch to be tested on a single lightcurve. To accomplish that goal, here we instead add a new parameter single_lc to Ensemble.batch

When single_lc is provided an object ID, the function provided to batch is executed on that single lightcurve.

This looks good, just have one main change that I think should be made.

[dougbrn]

I think it would be really helpful to also allow single_lc=True, where select_random_lightcurve is used to pick one for the user.

[wilsonbb]

Yeah that makes sense. To do that, I added an id_only parameter to Ensemble.select_random_timeseries so that it will only fetch the object id of a random lightcurve. But let me know if you would prefer that not added to the API and I can break that out differently.

[dougbrn]

Thanks! That looks like a good solution

[dougbrn]

Looks good!
