v0.3.2

Maintenance Patch

Apparently, ML-Kit is not FOSS.
Google ML-Kit powers both Quickie and Google Code Scanner.

• Replaced bundled Quickie with ZXing -
  • Reduced size (The app is tiny again)
  • No proprietary libs
• Still preparing for store listing.

Will share F-Droid download link when the app goes live.
