argparse version 0.7.0 - a CLI parsing library

[Andrey Zherikov]

Hi everyone,

I'd like to share that I've published a new version of 
[argparse](https://code.dlang.org/packages/argparse) library.
It's got some new features since my [first 
announcement](https://forum.dlang.org/post/zjljbdzfrtcxfiuzozty@forum.dlang.org) as well as some bug fixes:
- Support of the usage without UDAs
- Custom grouping of arguments on help screen
- Mutually exclusive arguments
- Mutually dependent arguments
- Subcommands

Enjoy it!

Regarding the future, I have some items in my todo list and here 
are few things I will work on next:
- Improve subcommand support (for example, default command)
- Shell completion

In case if anyone has thoughts about what feature is missed in 
the library, I'm open to the suggestions.
