Allow cursor based pagination

[anis-campos]

Hi,

Thanks for the good work, this version lib promising, it provides some useful perks compared to acsylla, mainly how it handles the dependency to scylla driver and the class parsing of the results.

However there is one thing missing, the cursor/state based pagination that is provided by scylla and possible in acsylla

Would it be possible to implement a cursor based pagination.

I'm thinking something like

class PaginationResult[T]:
   items: [T]
   has_more: bool
   state: bytes

async def execute_paginated(statement:str, page_size:int) -> PaginationResult: ...

WDYT ?
