* Creates a shallow clone of the passed object by applying an `fn` function

* to the value at the given path.

*
|
|
* The function will not be invoked, and the object will not change
|
|
* if its corresponding path does not exist in the object.
|
|
* All non-primitive properties are copied to the new object by reference.

* @sig [Idx] -> (v -> v) -> {k: v} -> {k: v}
|

* @param {Array} path The path to be modified.
