We have found that some Telegram classes are not in the file located what it is supposed to be located.

For example:

InputMediaVideo struct is located in api_params.rs and it should be located in objects.rs

InputMediaAudio struct is located in api_params.rs and it should be located in objects.rs

InputMediaPhoto struct is located in api_params.rs and it should be located in objects.rs
