importing_data: Parse common allele frequency data formats
In knifecake/fafreqs: Common Frequency Databases for Forensic Markers

Reads a tabular data file and generates a freqt object. Supports multiple common data sources:

read_popstr(filename, name = "")

read_nist(filename, name = "")

read_familias(filename, name = "")

read_strider(filename, name = "", origin = "")

`filename`	the path to the relevant CSV file
`name`	the name to give to the dataset
`origin`	(only for read_strider) which population group to choose

read_popstr: supports reading from CSV files downloaded from the pop.STR project website. No modification of the files is required.
read_nist: Supports reading from CSV files generated from NIST STRBase data. NIST data comes in MS Excel files with multiple sheets and additional formating. This function expexts a CSV file with only one of those sheets.
read_familias: Supports reading from a Familias frequency database file. The Familias importer does not support reading the number of individuals as it is not included in Familias data files.
read_strider: Supports extracting frequency data from the STRidER 2.0 XML database. Requires that the parameter origin is supplied and that it matches one of the keys in the STRidER database.
