the option `geoframe attach` doesn't work if variables already exist in the _shp file.

When trying to combine files that I had cleaned up, it ran in the following problem.

Here one can just "auto clean" shapefiles to contain just _ID, _X, _Y, shape_order.

I just posted an update that should solve this issue, I believe. geoframe attach no longer tries to add variables that already exist in the current frame.
