Collapsible GitHub project files

A Tampermonkey userscript to make the project file lists on GitHub collapsible.

Temporary solution to [Feature] Collapsible project files on Repository overview #109986.

And maybe also for toggle-files-button missing on "New Repository Overview" #6959 of refined-github.

Uses localStorage to be persistent on github.com domain when reloading page/browser.

Format: show NUM rows // DEFAULT

• show/hide NUM rows will show/hide the list when clicked
  • NUM displays the number of files/folders in the list
• DEFAULT show the current default collapse state and when clicked will cycle through the following options
  • auto (default) only collapse when a README (or LICENCE or similar) is displayed
  • expanded never collapse
  • collapsed allways collapse
  • last uses last collapse state (starts collapsed)
