2023.1.1 - Lang, tray, linux kb

Compatibility breaking changes:

• Support for one-symbol text to symbol. e.g. Tap("a", "enter") is
  now interpreted as one symbol rather than separate letters, even without combo brackets.
• Remove keyboard symbols: "return", "win"(now "os"), "virtual alt/shift/ctrl", "numpad_separator", "pause";
  change others from win32-specific to generic.

Major changes:

• Limited linux support: keyboard, except for language, should work for all linux OS
• Tray icon, for visibility and control
• Language support: transliterate, get and change input language
