Elevation script fixes

[KasiaKoz]

Fixes:

• clashing argument flags -ws
• import genet.utils.elevation as elevation being overwritten by elevation = args['elevation'] and preventing write_slope_to_object_attribute_file

As a bonus:

• gets rid of elevation_output_dir = os.path.join(output_dir, 'elevation') it's a needless extra folder (nothing gets saved anywhere else). User can decide if they want outputs saved to a folder called elevation or not

Looks good to me.

I think we say this every time, but it feels like we could do with some testing around the functionality in these scripts (which I think we've also talked about collecting into a CLI, right?).

yeah, it's been on the (jira) cards for a while (unfortunately I'm struggling to find the card right now - I already started matching up some example inputs to the scripts on the card)

Dunno about Jira, but there is #127 @KasiaKoz
