MadelineProto was updated to v5!

Introducing upload by URL, file renaming, parallelized downloads and uploads!

You can now use MadelineProto to rename Telegram files or upload them by URL: all uploads and downloads will be made 100% in parallel, 20 chunks at a time for maximum speed (value tweakable in the settings).
For more info, see the new file documentation.

Also introducing:
- Strictly typed, camelCase public API, now all methods can also be called in camelCase, with PHP type hinting for most parameters and return values.
- Full PHPDOC documentation for all the public API, for perfect documentation in your favorite IDE :)
- Several internal bugfixes, refactoring and general performance and stability improvements.
- Improved tests, to avoid backwards compatiblity issues with previous sessions when pushing.
- Clean composer dependencies, now you just have to require danog/madelineproto ^5.0 and nothing else in your composer.json!

Breaking changes:
- NONE :D; you don't have to change your code!
