Layout normalisation warning on a PanelGroup with 0 children

[MrSimmmons]

Building upon the example provided in #126 (using the exact same code, but with the most recent version of react-resizable-panels) you get a rather large console warning if you intentionally set the layout of a container to an empty array.

I wonder if this warning is necessary as the library seems to handle the scenario rather well bar some drag positioning shenanigans (which is likely a dnd-kit issue and not react-resizable-panels issue). Its also worth noting that this warning is not formatted correctly for scenarios where you are setting the size to 0. So I wonder if its safe to say that the normalisation can be performed on a PanelGroup if its final state is empty.

I’m not opposed to a different warning in that case! Seems like an empty panel group is probably still something worth warning about (in Dev mode) but I agree that message is goofy

The warning has been removed entirely for empty panel groups as of v2.1.2
