v0.6.0f

Format/design notes:

• New configuration mode B has split symbol and color decodes. This means that even if the colors are completely wrong (or the image is black+white!), we can still make progress.
• the new format also allows better color correction => better performance under a larger variety of conditions
  • there are some narrow circumstances where the old mode 4C might still be better
• removal of 8-color support (for now?)

Graphical app updates:

• instead of "4/8", the toggle at the bottom right corner of the app is now "4C/B". An 8 kind of looks like a B, but I went above and beyond the call of duty to change it.
• adjusted the "extract success but failed full decode" color introduced in 0.5.15. It is now yellow. Very exciting.

Bugfix:

• fixed a race condition in how the color correction matrix was being updated
