Sample file updated.

In release 38984b10ff this file is broken in base parts, like the original one.

In release 0bbff8a711 this file is different, with no distinction between the object.

[190322_rhino_to_blender.obj](https://archive.blender.org/developer/F6864830/190322_rhino_to_blender.obj) Sample file updated. In release 38984b10ff7b this file is broken in base parts, like the original one. In release 0bbff8a71138 this file is different, with no distinction between the object.

Adding screenshots.

In older Blender 2.80 release, OBJ import works properly: file is imported, with distincted/separated elements. I can select one of them instead others. In Collection I can see elements, listed one by one, named like the layers in original file (in Rhino).

In release 0bbff8a711, OBJ import make ONE entitity, joining elements in one. No separation between elements. I can't select no one of them, but only the entire imported file. In Collection I see only one element, named as the file that I imported.

Not sure why Rhino exports these as groups [and not objects] but I guess this has been decided upon and is thus working as expected, closing...

Just to make sure, I'll raise awareness to @JacquesLucke and @mont29 [so they have heard of Rhino acting like that]

"You have to enable Split by group"

It works, but not in the same way respect older release. For my purpose it's ok.

Last screenshot, showing differences.

Thank you.
