As a result of an investigation by https://github.com/uweschulzweida, I discovered a significant bug in the NCZarr cache management. This PR extends the above PR to fix that bug.

Change Overview

  • Insert extra checks for cache overflow.
  • Added test cases contingent on the --enable-large-file-tests option.
  • The Columbia server is down, so it has been temporarily disabled.
