Minor addition for a common situation.

Describe the solution you'd like

What about having a channel= keyword argument for conda_install so that one could write channel="conda-forge" if selecting a channel? It would be a bit more natural than "--channel=conda-forge", I think, and likely is very common.

It is possible to set multiple channels - this is required for bioconda, for example. This could be an iterable, channel=["conda-forge", "bioconda"]. Maybe the keyword should be "channels" and always takes a list?
