Cannot get correct information for Bittensor validator

[antonr-p2p]

Describe the bug

I try to get info about validator. Most of the fields get correct info, but not all of them.
I use get_delegate_by_hotkey method for which return_per_1000 and total_daily_return options return either 0 values or incorrect ones.

I tried to use get_delegates method as well, but it look like there is an issue with code in your library around decoded = bt_decode.DelegateInfo.decode_vec(vec_u8) in core/chain_data/delegate_info.py

So both methods either don't work or return incorrect info. Please fix or provide any other way.
Thanks in advance!

To Reproduce

WAY 1:

import bittensor as bt
sub=bt.subtensor()
v=sub.get_delegate_by_hotkey(hotkey_ss58='VAL_HOTKEY')
v.total_daily_return
## τ0.000000000
v.return_per_1000
## τ0.000000000

WAY 2:

from bittensor.core.chain_data import DelegateInfo 
import bittensor as bt

sub=bt.subtensor()
delegates: List[DelegateInfo] = sub.get_delegates()
>>>Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/anton/bt/bt_prod/lib/python3.10/site-packages/bittensor/utils/networking.py", line 198, in wrapper

    decoded = bt_decode.DelegateInfo.decode_vec(vec_u8)
TypeError: argument 'encoded': 'list' object cannot be converted to 'PyBytes'

Expected behavior

I get correct values for validator daily return and return per 1000 TAO.

I found one more issue. registrations value is also incorrect.
Please check that both get_delegate_by_hotkey.registrations and get_netuids_for_hotkey provide incorrect info about SNs 54 and 55. Checking with is_hotkey_registered_on_subnet function.

>>> import bittensor as bt
>>> sub=bt.subtensor()
>>> v=sub.get_delegate_by_hotkey(hotkey_ss58='5HRB5xi9W1yEdJGEWPsgtH71mPjAvN2Z9HxNvRMMcK5kXuW2')
>>> v.registrations
[15, 16, 37, 49, 54, 55, 56, 57, 60, 61, 62]
>>> sub.get_netuids_for_hotkey(hotkey_ss58='5HRB5xi9W1yEdJGEWPsgtH71mPjAvN2Z9HxNvRMMcK5kXuW2')
[15, 16, 37, 49, 54, 55, 56, 57, 60, 61, 62]
>>> sub.is_hotkey_registered_on_subnet(hotkey_ss58='5HRB5xi9W1yEdJGEWPsgtH71mPjAvN2Z9HxNvRMMcK5kXuW2',netuid=54)
False
>>> sub.is_hotkey_registered_on_subnet(hotkey_ss58='5HRB5xi9W1yEdJGEWPsgtH71mPjAvN2Z9HxNvRMMcK5kXuW2',netuid=55)
False
>>> sub.is_hotkey_registered_on_subnet(hotkey_ss58='5HRB5xi9W1yEdJGEWPsgtH71mPjAvN2Z9HxNvRMMcK5kXuW2',netuid=56)
True

So I'm confused why hotkey is shown as registered when it doesn't have hotkey registered.
