[feature] allow user to enter voxel resolution (alternative to scaling)

[xgui3783]

if the user knows voxel resolution, they should be able to enter it (instead of scaling)

@xgui3783 Is there any way to set a specific resolution on neuroglancer?

[xgui3783]

Voxel resolution.

Not specifically, but it can be calculated, and applied to the affine.

@xgui3783 Thanks. So we have to get the current resolution and calculate the scale with new values?

[xgui3783]

We can get native voxel resolution from /info (unless voluba image service provide it)
