0.23.0

Added

• mirrors sync works both ways. Edits and ticks made in Google come back into the local files: a Markdown
  file changes only on the lines of changed paragraphs, so its own markers, spacing and code languages stay; a CSV
  or TSV file takes Google's cells and keeps how it spelled unchanged values (1.50 stays 1.50). The same
  paragraph or cells changed on both sides is a conflict: that file is left alone, the rest sync, and the report
  shows each side's text, when the file changed and Google's last revision time and editor. --keep local,
  --keep google or --keep both settles it. Every mirrored file is now read from Google on each sync. XLSX files
  do not take changes back; a Google edit to one stays a conflict until --keep local.

Changed

• --replace keeps Google's edits that do not collide. It now means --keep local plus creating deleted
  files again, so only conflicting parts are overwritten, and Google's other edits come back into the file. A Doc
  with pending suggestions is refused whatever side is kept: suggested text would read as accepted.
