Add machine readable output flag

[leny-mi]

Clear and concise description of the problem

As a user of taze, I'd like to use taze in multiple steps within short scripts where I can automate some bumps depending on the output from taze. Currently this output seems to be only designed to be readable by humans. For use in scripting I'd like to have the taze output machine readable.

I'd be happy to contribute if this is something you consider generally useful!

Suggested solution

I could imagine a --json flag that replaces the current output with a machine readable json output.

Alternative

I could have taze just make the change and look at the diff but that seems to be a bit wasteful.
