Spectral Library: name of default field should be changed

[Fabian Thiel]

I think name is a fieldname that should be usable by the user, hence I would change the auto generated field’s name to something like info, description, desc, identifier, file_xy_crs or anything else…

[Benjamin Jakimow]

name can be editied by users like any other field.

Initial names given to SpectralProfiles selected in maps are <file basename><geo-coordinate>, e.g. enmap_berlin.bsq 386102.94471264374 5818809.131609195 EPSG:32633

This might be shortened to <file basename><pixel-coordinate>, e.g. enmap_berlin.bsq 100,200
