Non-breaking changes: - Adds filter logic to the `list` method to support the `options.filter` argument, fixes #581 - Adds basic document format version tagging and migration support - Migrates existing stored metadata to stored as BSON objects rather than binary data. - Includes a change to `checkpoint-sqlite` and `checkpoint` libraries to centralize an array that I'm using in multiple packages to sanitize filter inputs. - Stores `channel_values` by version on change, respecting the `newVersions` argument to `put`, fixes #595 - Populates `pendingWrites` and `pending_sends` correctly, fixes #589 - Updates `checkpoint-validation` to no longer skip tests that exercise the above fixes --- <sub>🔄 This issue represents a GitHub Pull Request.
