Telegram cli and chat backup
Complete procedure can be googled from [here](https://www.haykranen.nl/2014/12/02/howto-backup-your-telegram-chats/).
Some comments on run:
- don't just download it from github as a zip - there are patches, which will not be included in it (tgl and recursive directories). Solution as written in doc for tg-cli: git clone --recursive https://github.com/vysheng/tg.git && cd tg;
- when compiled inside homebrew it shows an error: unused function 'get_peer'. Solution is [here](https://github.com/vysheng/tg/issues/996). It's simple - comment three strings in lua-tg.c and recompile;
- to get chat history with all photos and videos set following parameters in telegram-history-dumpconfig.yaml to true:
- copy_media: true
- download_media ... photo, video, audio ... true.
