* Wrapper function to handle caching of memoized requests that recieve objects as args.
|
|
* React Cache will use shallow equality of the arguments to determine if there is a cache hit,
|
|
* therefore we need to stringify the arguments to ensure that the cache works as expected.
|
|
* This function will handle the stingification of the arguments, the caching of the function,
|
|
* and the parsing of the arguments back to their original form.

* @param fn - The function to memoize
