Fix delegate info methods to return correct values

Fixes opentensor#2564

Fix the issue with `bt_decode.DelegateInfo.decode_vec` in `bittensor/core/chain_data/delegate_info.py` to handle the decoding of `vec_u8` correctly.

* Add a new method `from_vec_u8` to decode `vec_u8` and return a `DelegateInfo` object.
* Update the `list_from_vec_u8` method to correctly decode `vec_u8` and return a list of `DelegateInfo` objects.
* Ensure that `total_daily_return` and `return_per_1000` are correctly decoded and returned.

Update `bittensor/core/chain_data/delegate_info_lite.py` to handle type conversions and ensure correct data types.

* Add a new method `from_raw_data` to create a `DelegateInfoLite` instance from raw data with proper type conversions.
* Ensure that `registrations` and `validator_permits` are lists of integers.
* Ensure that `take` is rounded to 6 decimal places and `nominators`, `return_per_1000`, and `total_daily_return` are integers.
