refact: remove memoize

[brandon-ja]

So it turns out memorize has a bunch of problems that are not easy to fix.

• Currently the internal cache is leaky meaning entries never exit the cache once they get added.
• Adding a cleanup method isn't super easy given you need to configure how often the cleanup logic runs.
• Even if a cleanup method is added it will likely be in a go-routine which we need a context to handle otherwise we risk leaking that go routine.
• Supporting deletes for persist.Store types would require adding more complexity to that interface, further complicating every implementation of the persist.Store
• This package uses functional style code, which is fine when simple, but hand to integrate into non-functional code as it's complexity grows.

Rather than try to solve these issues, I think removing this package is the better option. This will allow the cachin to stay simple, functional and extensible.
