Subject: Partially implement `partial_correlation_recursive`

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/computations/partial_correlations.py: Implement one path for the
  `gn3.computations.partial_correlations.partial_correlation_recursive`
  function.
* gn3/settings.py: Add a setting for how many decimal places to round to
* tests/unit/computations/test_partial_correlations.py: Update test to take
  the number of decimal places into consideration

  Implement a single path (where the z value is a vector and not a matrix) for
  the `partial_correlation_recursive` function.
