fixed type hints of hash methods

[amirreza8002]

i do have one problem
hgetall() either returns a dict of bytes: dict[bytes, bytes], or an empty dict
python doesn't have any way to type hint empty dicts
so i either have to do what i did here and just type hint as dict, or do Union[dict[bytes, bytes], dict]

which do you think is better suited?

p.s: i'll provide examples of this methods' types in a coment

examples:
hset:

>>> v.hset("hash1", "foo", "bar")
1
>>> v.hset("hash2", mapping={"aa": "bb", "cc": "dd"})
2

hget:

>>> v.hget("hash1", "foo")
b'bar'
>>> v.hset("hash1", "baz", 2)
1
>>> v.hget("hash1", "baz")
b'2'

hdel:

>>> v.hdel("hash1", "foo")
1
>>> v.hdel("hash2", "aa", "cc")
2

hexists:

>>> v.hexists("hash1", "foo")
False
>>> v.hexists("hash1", "baz")
True

hgetall:

>>> v.hgetall("hash2")
{}
>>> v.hgetall("hash1")
{b'baz': b'2'}

hincrby:

>>> v.hincrby("hash1", "baz")
3
>>> v.hincrby("hash1", "baz", 4)
7

hincrbyfloat:

>>> v.hset("hash1", "foo", 2.2)
1
>>> v.hincrbyfloat("hash1", "foo", 4.1)
6.3

hkeys:

>>> v.hkeys("hash1")
[b'baz', b'foo']

hlen:

>>> v.hlen("hash1")
2

hsetnx:

>>> v.hsetnx("hash1", "foo", 1)
0
>>> v.hsetnx("hash1", "new", 1)
1

hmset:

>>> v.hmset("hash2", {"a": "b", "c": "d", "e": 3})
<python-input-23>:1: DeprecationWarning: Valkey.hmset() is deprecated. Use Valkey.hset() instead.
  v.hmset("hash2", {"a": "b", "c": "d", "e": 3})
True

hmget:

>>> v.hmget("hash2", ["a", "c", "e"])
[b'b', b'd', b'3']

hvals:

>>> v.hvals("hash2")
[b'b', b'd', b'3']

hstrlen:

>>> v.hstrlen("hash2", "a")
1
