Subject: Handle type-coercion exceptions

* gn3/computations/qtlreaper.py: handle exceptions

  Sometimes, the values being parsed are plain strings and cannot be cast to
  the float types. This commit handles that by casting only those values that
  can be cast to float, and returning the others as strings.
