Webhook avatar cannot accept bytes type due to TypeError

[Bohaska]

Summary

When adding an image in bytes type to a webhook using the create_webhook command, I run into a TypeError.

Reproduction Steps

I used the text_channel.create_webhook() function with an avatar attribute with value type bytes.

Minimal Reproducible Code

nextcord import Interaction, SlashOption, Embed, Colour, Webhook
from nextcord.ext import commands
import logging

bot = commands.Bot()


@bot.slash_command(description="Creates a webhook", force_global=True)
async def webhook_test(interaction: Interaction):
    await interaction.response.send_message("Setting up webhook...", ephemeral=True)
    avatar = open("avatar.jpg", "rb")
    webhook = await interaction.channel.create_webhook(name="Test webhook", avatar=avatar, reason="Successfully "
                                                                                                  "created webhook for "
                                                                                                  "testing.")


logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s')
logging.debug('Start of program')

bot.run("bot_token")

Note: Needs an image named avatar.jpg in the same folder as file.

Expected Results

I expected the command to create a webhook with the avatar included.

Actual Results

I got a TypeError: object bytes can't be used in 'await' expression

The full traceback is below:

A buffered IO is not currently a valid type that the function accepts.

You can pass bytes, but to do that, you'd call read on it beforehand.

Example:

avatar = open("nextcord-logo.png", "rb").read()
webhook = await channel.create_webhook(name="Testing", avatar=avatar)
await webhook.send("Hello, world!")

Another option is to use nextcord.File:

avatar = nextcord.File("nextcord-logo.png")

I have tested both of these approaches and they are working as expected.
