1.11: KataGo upgrade, Tsumego Frame, Turkish translation

New Features

• Included KataGo upgraded to v1.11 see improvements here
• Tsumego Frame, thanks to @kaorahi #498
• Prune branch option in the move tree. This removes all side branches leading up to the selected node.
• Turkish Translation, thanks to "Bora Zafer"
• Keyboard shortcuts for contribution
  • Esc gracefully aborts contribution, finishing current games
  • Pause pauses/resumes contribution
  • To forcefully exit KataGo without finishing games in progress, just quit KaTrain itself
• Estimated territory restyling, thanks to @milescrawford in #487
• High precision score near 0, thanks to @pdeblanc in #514
  • This enables an option to show score estimates near 0 to 2 significant digits, which can be enabled under analysis settings.

Technical changes and fixes

• Upgrade to Kivy 2.1
  • The MacOSX build should hopefully be improved by this.
  • Python 3.6 support was dropped.

Installation

• Windows users can simply download and run the KaTrain.exe file attached, or download the KaTrain.zip file and run the .exe in that (which is slightly faster to start up)
• macOS users can use the attached KaTrainOSX.dmg (open, drag .app to applications). The first time you start the app, you will need to control-click the app in finder to allow installation. Note that on the newer Macs with M1 architecture, you still need to brew install katago, or compile katago yourself.
• Linux and macOS users can install using pip3 install -U katrain

After installing the program for the first time, it is recommended to check general settings (F8) and download the latest katago models.
