Error in natural.JaroWinklerDistance() when missing optional options parameter

[dandybytes]

The example in the following documentation link seems to imply that the natural.JaroWinklerDistance() function can be used with two required arguments (i.e. the two strings to compare) and an optional options parameter:

https://naturalnode.github.io/natural/string_distance.html

However, according to the function I can see in code, the options parameter is required. If you do not pass it, then the function throws an error, because options === undefined and options.ignoreCase is undefined.ignoreCase, which obviously fails.

https://github.com/NaturalNode/natural/blob/c2389f2a17faae9582a1a0f41402c68407ccb378/lib/natural/distance/jaro-winkler_distance.js#L109C1-L109C30

A) If the options argument is indeed optional, then I would use the optional chaining operator in all applicable cases (i.e. options.ignoreCase ---> options?.ignoreCase and options.dj ---> options?.dj)
B) If the options parameter is meant to be required now, then I would update the documentation and the function comments accordingly, and maybe add a condition to that function that checks for the presence of the options and, perhaps, use the optional chaining operator for extra safety anyway.

By the way, those function comments would greatly benefit from proper JSDoc annotations, in addition to clearer explanation of the data structure of that options parameter.

Otherwise, thanks for the great job, guys!
