* feat: add typed versions of getMap and getList to Loro class
This commit adds `getTypedMap` and `getTypedList` methods to the `Loro` class, which allow for accessing maps and lists with type information. It also adds corresponding `getTyped`, `insertTyped`, and `setTyped` methods to `LoroMap` and `LoroList`. This makes it easier and safer to work with Loro's data structures.
