[Feature Request] support changing directory

[oboenikui]

Currently, even if the current directory is changed as a result of executing command, it is not kept in the next step.

It would be very convenient to have a means to save the directory of the execution result or to execute directory changes between steps.

Alternatively, if we can execute our own Go method between steps, we could achieve our goal by calling os.Chdir.

@oboenikui thank you for the feature request! I agree it would be great to be able to set the working directory. Do you like to propose a PR for it?

@saschagrunert
Thank you for confirming.
I have not worked on it yet, but if you prefer someone to submit the PR, I'm willing to do so.
If you prefer to work on it yourself, I respect that decision because I have never written much golang code.
