get stress table output from OVERVIEW.OUT

[jeevakir]

added a function to get stage-wise stress output from OVERVIEW.OUT. The function handles only the first run. Will add functionality to create table for all runs with run number as index. Please make changes if anything is needed. thanks for the package.

Hi! thanks for your contribution. I'm reviewing the request and the changes in the code is causing some of the tests to fail. I'll modify what is causing the issue and then I'll merge it. Also, instead of saving the output in _ouput['OVERVIEW'], I'll create a new element in the output with the name of "stress". This is due to the fact that the overview file not only contains stress tables, it also contains other type of information that may be useful for other users.

After reviewing I made a couple changes. It seems Perennial forages don't generate the overview file, that was causing some issues. Now, I'm adding the stress into a new DSSAT.stress_table attribute. The OVERVIEW file is saved in the output attribute as the lines of the raw file. However, I see that there is some problems with the stress table, it seems that the Dev stage column is not being created is it's supposed to be. You can check what I mean in one of the tests, maybe the Maize test is the best example to work with.

I just pushed the changes I made, and as soon as we make sure the new function correctly creates the stress tables for all crops, then I'll proceed to merge and update the PyPI package.

Thanks again for your contribution.

Hi, Thank you for the library again. Your changes makes more sense as it will be easier to understand than naming it as _output['OVERVIEW'] . Sorry for raising an incomplete pull request without running tests. I just created it quickly as a favor. I will test it from my side. If possible i will try to expand the _get_overview_stress() to include stress tables for all runs instead of just the first run. Once again, my apologies for the improper pull request. Please let me know if there is a specific way to go about it for indexing the tables.
