Make it actually performant w `ctypes`

Current implementation is focused on functionality - to have strict types with relevant features like serialization and json parsing - till we figure out what's actually important to have.

Though we have been minimal fn to have least overhead to be performant, this still is just a wrapper around python types - which is not the correct way to implement types. C already provides the types we need, and having a C extension should be much more performance and the correct way to implement this
