[Bug]: fetch_chatters_color not handling user without color

[MrChuw]

What actually happened?

fetch_chatters_color gives an error if the user does not have any color set.

unpack requires a buffer of 3 bytes in line:

TwitchIO/twitchio/utils.py

Line 480 in 5774dee

rgb: tuple[int, int, int] = struct.unpack("BBB", bytes.fromhex(value))

because the received value is an empty string.

What did you expect to happen instead?

Maybe return all the color values as None. Or return None for respected user_id instead of ChatterColor

Minimum reproducible example:

tmi_user = await ctx.bot.fetch_user(login=name)
tmi_color = (await ctx.bot.fetch_chatters_color([tmi_user.id]))[0]
color = tmi_color.color

Steps to reproduce the problem

Replace name with "cool_name" it has no color set.
