Manpage for cht.sh (command line client)

Hi,
I created an [ITP](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1053005) for command line client (cht.sh) in Debian, but there isn't a manpage.
So I created one using the txt2man. Feel free in using this or create another one, but if you will use this one in attach, please provide also the file `.txt` as it was generated by 3rd application and the original source needs to be available.
[manpage.tar.gz](https://github.com/chubin/cheat.sh/files/12731998/manpage.tar.gz)

Thanks

Start by reviewing the attached manpage.tar.gz, including the generated manpage and its .txt source from txt2man. Check how the cht.sh command-line client is documented and where a manpage and source file belong; done means the manpage is included with its editable source and accurately documents the client.
