hvtiRdatabuild 0.2.3

• New publish_dataset(). A programmer can publish a mutable clinical-data
  draft as an immutable dated release. Publication preserves the draft bytes,
  verifies that the staged copy is readable, records its checksum and shape in
  dataset-catalog.yml, and serializes concurrent publishers with a catalog
  lock. Same-day corrections receive revision filenames; retrying identical
  bytes is idempotent, including recovery of a file moved before a failed
  catalog write.

• New withdraw_dataset_release(). Withdrawal records a reason and an
  optional replacement in the catalog without changing or deleting the
  published file. The package now requires hvtiRutilities 1.3.1, whose study
  workflow discovers, reviews, and explicitly adopts these releases.
