Read PHONON version number from stdout

[atztogo]

PR #633 is critical. To merge PR #633, @sphuber suggested to check version number, but PHONON parameter output doesn't contain the version information.

This PR is made to read the version of PHONON. The code is taken from parse_output_base method. Here I follow parse_output_base's naming of the key 'code_version', but this may be inconsistent with 'creator_version' in PW, though I don't know what exactly means 'creator'.

Thanks! @atztogo
The implementation is good, but you should run tests/parsers/test_ph.py with --force-regen to count this new attribute.

As for 'creator_version' I believe it is the same as the code_version, while 'creator_version' only parsed in pw with XML format. Let's see what @sphuber says.

Thanks @unkcpz. I could not succeed to run the test. I simply don't understand the testing manner in aiida-quantumespresso. I looked into the documentation, but didn't find a good introduction (https://aiida-quantumespresso.readthedocs.io/en/latest/devel_guide/parsertests.html#running-tests). I would like you to include something like this PR to your PR #633 by hand (i.e., copy and paste etc) if you are fine. Then I will close this PR.

Thanks @atztogo . I am updating the PR of @unkcpz with the necessary info and then merging it. We can keep this open and I can add a quick test for you. No need to close it.

I came back to this PR, but I cannot actually find in #633 where I would have called for parsing the version? It is not actually being used in the code anywhere for checks. So I think we can close this. Thanks nonetheless @atztogo !
