/**
* Maps each element of a Set based on a provided key-generating function.
*
* This function takes a Set and a function that generates a key from each value.
* It returns a new Map where the keys are generated by the key function and the values are
* the corresponding values from the original set. If multiple elements produce the same key,
* the last value encountered will be used.
*
* @template T - The type of elements in the Set.
* @template K - The type of keys to produce in the returned Map.
* @param set - The set of elements to be mapped.
* @param getKeyFromValue - A function that generates a key from a value.
* @returns A Map where the generated keys are mapped to each element's value.
*
* @example
* const set = new Set([
*   { type: 'fruit', name: 'apple' },
*   { type: 'fruit', name: 'banana' },
*   { type: 'vegetable', name: 'carrot' }
* ]);
* const result = keyBy(set, item => item.type);
* // result will be:
* // Map(2) {
* //   'fruit' => { type: 'fruit', name: 'banana' },
* //   'vegetable' => { type: 'vegetable', name: 'carrot' }
* // }
