Pick dataset icon based on shape in explorer

[axelboc]

I went through a lot of icons from multiple icon sets available through React Icons but I think it was worth the effort. The new icons help match silx view more closely:

H5Web before	H5Web after	Silx

I keep the "layers" icon for 4D+ datasets:

H5Web	Silx

Empty datasets (i.e. with a null shape) now have their own icon as well:

H5Web	Silx

We don't currently support array datasets with zero dimensions, but if we do in the future, I think a square brackets icon like [] could work.

Holy moly, that looks so cool ❤️

1D and 2D icons could be slightly bigger if that's not too difficult to do

I'd have to revert to an custom Icon component instead of a getIcon utility. Possible, but a little more verbose. Let me know if you think it's worth it.

Nah, let's leave it like this for now and let's see how it goes first.

A quick win that got lost in the backlog... 😅
