i3status-rust fails to build unless libpulse is installed

[akdjka]

I just wanted to install i3status on my system. Linking failed with

  = note: ld.lld: error: unable to find library -l:libpulse.so.0
          clang-15: error: linker command failed with exit code 1 (use -v to see invocation)

Fine, I don't have libpulse installed. And I don't want to. But this requirement is not documented in https://github.com/greshake/i3status-rust/blob/master/doc/dev.md and I think it should be.

Also, making libpulse dependency optional would also be welcome.

It is, but it's on by default. Did you compile with --no-default-features?

But this requirement is not documented

Fixed

With this switch it builds fine. :)
