Added write method to _Config class.

Claudio,

I think it would be handy to save the configuration made in an interactive session, so I added a write method to the _Config class. Can you check it?

Claudio,
I'm making a new notebook using one of the examples in sourcespec_testruns.
I'm using test_CDSA as an example.
First, I updated sourcespec.conf to sourcespec2.
I then read the configuration file interactively, along with the trace data, quakeml data and inventory. However, when I start the inversion, this results in the following error:

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
Cell In[13], line 2
      1 config.options.outdir = None
----> 2 result = ssp_run(st, inventory, event, picks)

File E:\Home\_kris\Python\cloned_repos\sourcespec2\sourcespec2\source_spec.py:110, in ssp_run(st, inventory, ssp_event, picks, allow_exit)
    108 print('Augmenting event')
    109 augment_event(ssp_event)
--> 110 print(ssp_event.hypocenter.vp)
    111 augment_traces(st, inventory, ssp_event, picks)
    113 # Deconvolve, filter, cut traces:

AttributeError: 'SSPHypocenter' object has no attribute 'vp'

Investigating this issue, I discover that this is because vp_source and similar parameters are strings, which results in a silent error in the _hypo_vel function.
It turns out I should have ran a validation of the config object after reading the file.
However, when I do this, I get a new error:

---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)
Cell In[4], line 2

    637 self.update(config_obj.dict())

    364         msg += f'\nInvalid value for "{entry}": "{config_obj[entry]}"'
--> 365     raise ValueError(msg)
    366 if not test:
    367     raise ValueError('No configuration value present!')

ValueError: 
Invalid value for "mis_oriented_channels": "Z, 1, 2"

Invalid value for "t_star_min_max": "0.0, 0.1"
Invalid value for "Er_freq_range": "noise, noise"

I don't understand this one. The values for these parameters seem to be in agreement with the specs.
Any ideas?

Here is the configuration file:
source_spec.conf.txt

OK, I solved it by splitting strings containing lists into string lists before validating.
Maybe I'm missing something, but this should probably be done in setup.configobj_helpers.read_config_file.

Thanks Kris, I fixed a problem which prevented running tests on pull requests against v2 and force-pushed.

Will come back later today, when the tests are done (and hopefully pass) 😉
