DeprecationWarning: DataFrameGroupBy.apply

[paulschreiber]

Fix the code causing this warning:

  /home/runner/work/soil-id-algorithm/soil-id-algorithm/soil_id/utils.py:2162: DeprecationWarning: 
DataFrameGroupBy.apply operated on the grouping columns. This behavior is deprecated, and in a future 
version of pandas the grouping columns will be excluded from the operation. Either pass 
`include_groups=False` to exclude the groupings or explicitly select the grouping columns after groupby to 
silence this warning.
    result = df.groupby("compname_grp").apply(process_group).reset_index(drop=True)
