Calculate Jaro-Winkler distance for two strings `str_1`

and
`str_2`

1 | ```
jaroWinkler(str_1, str_2, weight_threshold = 0.7, num_chars = 4)
``` |

`str_1` |
first string for calculating the distance |

`str_2` |
second string for calculating the distance |

`weight_threshold` |
percent to apply the Winkler modification |

`num_chars` |
size of the prefix to be concidered by the Winkler modification |

The Jaro-Winkler distance metric is a string edit distance. The Jaro-Winkler distance metric is designed and best suited for short strings such as person names. The score is normalized such that 0 equates to no similarity and 1 is an exact match.

the Jaro-Winkler distance between the specified strings
