Column name mapping ignored for missing in left/right

[MariusMerkleQC]

When I provide a column_name_mapping to compare_tables(), it uses the mapping to compare the values in the respective columns and fills the section "Column Matches" properly. For example, if column_name_mapping = {"a": "b"}, the values of column "a" in the left table are compared with the values of column "b" in the right table.

However, it still fills the lists "Missing in left: ["b"]" and "Missing in right: ["a"]". I think it would be more intuitive for a user to remove the column names from these missing lists. If I provide a column_name_mapping, I always remove the values contained in the mapping from these lists, to see which columns are actually missing.
