Use parallel standalone generated quantities
Submisison Checklist

./runCmdStanTests.py src/test - [x] Declare copyright holder and open-source license: see below
Summary:
Note the line change # here is just from adding the test files. Theres about 100 code line changes in total
This swaps out the old generated_quantities function call for the new parallel version.
This is pretty straightforward besides the changes to get_num_chains. For generated quantities, we don't have the user pass the number of chains, so we need to do some deduction to figure out how many chains the program will be running. We use similar logic to how we figure out the number of inits. If the user supplies just a my_file_name.csv then we assume it's just 1 chain. But if a user supplies my_file_name_{id}.csv we search for my_file_name_{{id} + 1, {id} _ 2,..., {id} + N} sequentially until we cannot find anymore files. The total number of files is the total number of chains.
Intended Effect:
Allow users to call generated quantities in parallel.
How to Verify:
I only wrote one test in generated_quantities_test.cpp that checks that the program does not error out. Is that sufficient?
