\description{
This function shortenes the column names using regex. When flattening a list from .json the resulting colums are named like "diagnoses.treatment.updated_datetime". Each period indicating a level of the list.
For better readability everything in front of the last period is deleted.

z1 <- rename_margin(df, 2, "\\\\.", "-") #change all "." to "-"
