v1.3.0

• Side panel (menu button, top left) replaces the bottom bar, with tabs inside each section. The back gesture now
  returns to the previous screen instead of closing the app.
• Manage your Spoolman from the app: add, edit and delete manufacturers, filaments and spools, archive spools,
  weigh a spool in, create several spools at once or duplicate one.
• Spoolman's public filament database: matches show up when you search for a filament, and you can browse by
  manufacturer and add several filaments (and new manufacturers) at once.
• Tags: see, link and unlink the tags on any spool or filament; Find a spool opens what a tag is linked to;
  Tag audit lists spools with missing, unlinked or stray tags; new setting Link tags when reading.
• QR labels: print them from the new Labels section (sheet or label printer, any size) and scan them with
  the camera (Read → Scan a label). They use Spoolman's own codes. The camera permission is asked for only when you
  scan.
• Report scans to Spoolman (off by default) makes the phone act as a Spoolman tag reader, so Spoolman's web page
  can jump to what you scan. A how-to shows when you turn it on.
• Write list: new Needs attention, Low, Material and Location filters.
• Tags per spool is now a number from 1 to 6 (still 2 by default), and the Done screen closes after a number of
  seconds you choose, 3 by default.
