Description:

 """ Collect a sample of clients given an input column Filter dataframe based on the modulus of the CRC32 of a given string column matching a given sample_id. if dataframe has already been filtered by sample_id, then modulo should be a multiple of 100, column should be "client_id", and the given sample_id should match the value previously used, optionally plus multiples of 100.

 selects a 1/modulo sampling of dataframe column (str):
 name of a string column to sample on sample_id (int):
 modulus result to select for sampling Returns: A DataFrame sampled on the given inputs. """
