Includes several fixes and improvements to Vamana, primarily:

  • Edge case and bug fixes for Vamana index build (details below)
  • Documentation added for Vamana
  • experimental namespace removed

The edge case fix adds padding to all shared memory size and offset calculations so any dataset dimension is supported (tests added that verify this). A bug was also fixed with the L2 distance metric causing incorrect results in some rare cases.

This PR addresses the most pressing items in #393 and stabilize the index construction sufficiently to remove the experimental namespace.
