Update memorize function

[mpcarolin]

The JSUtils memorize function currently has some behavior I think is non-intuitive or borderline buggy. I have some ideas about fixing this soon, but I'm writing this here so as not to forget.

• by default, if you do not define the getCacheKey function, it memoizes the function call using only the first argument as its cache key. I would expect it to use all the arguments by default.
• the cache value is set using a computed property name:

{
  [key]: value
}

• this implicitly calls key.toString() to get the actual cache key. However, if the argument is an object, to key will always be [ object Object ], which would reuse the same cached value for different input.
• I would rather it use a shallow-equal comparison for objects, like react's useMemo hook.

Yah, I remember you bringing this up a while ago. It's good point.
And since it was brought up, A shallow equal helper has been added to the library, so we could just reuse that.
Feel free to create an issue is Jira, so we can get it done
