Add note in docstring for functions that modify original df from /muttlib/ files except /muttlib/dbconn/*
Some of the functions that deal with df, make changes in the passed df and it will be wise to write some kind of note or something to warn the user of such modification.
This issue was desagregated from this one to check only df changes on /muttlib/* files without /dbconn folder.
Warning to add to the docstring should be like this: "Warning! Be aware this function modifies the given Dataframe, so please send a copy of the original if you want it to remain unmodified"
