bump clap and use crate_version macro

[akshatagarwl]

There is also a crate_authors macro that can be used in a similar way

@humancalico Looks good, but you need to run cargo fmt

[utam0k]

@humancalico hmm. There was some suspicious log on the CI, and it was taking quite a while to test. I want to confirm, did the test passed on your machine?

[akshatagarwl]

@utam0k the tests are kinda flaky. On three different runs I got different results each time and different tests failing

[utam0k]

Oh.. Sorry, I create the PR to fix the unstable tests.
#267
However, I have a feeling that this error of ci at this PR is something different.

@humancalico We have some problems with code coverage right now, so we have disabled it until further investigation. Please rebase and try again.

[akshatagarwl]

@Furisto still getting the same failure
