  - Major performance enhancements, using indexes for the regression
  - update_R - Generate blocks correctly #214
  - lambda optimization - Lambda as a function of E.
  - New alpha parameter to estimate lambda during runtime
  - fail-safe for < 40 cells dataset . Setting block_size=0.2. Refuse to run with < 6 cells.
  - added progress bar for the integration step.
# harmony v1.1.0 - Oct 12 2023
  - update_R bug - All cells are corrected exactly once per invocation
  - Improved documentation RunHarmony generc
