Media upload to fix #2624

Todo.

It seems like uploads for InputRichBlockAnimation, InputRichBlockAudio, InputRichBlockPhoto, InputRichBlockVideo, InputRichBlockVoiceNote will not work
InputRichMessageMedia also.

Apihelper would also need altering, for functions like send_rich_message, send_rich_message_draft, and edit_message_text

replace_sticker_in_set should use convert_input_sticker to upload stickers similar to add_sticker_to_set
checklist in send_checklist needs .to_dict()
both in apihelper & asyncio_helper files
