1.20.0 - 13.6.2022

• Lua: upgrade to 5.4, replacing tolua++ bindings with LuaBridge2.6 library, extending some bindings
• Lua: bindings slightly modified (required by upgrade), refreshed docs, added test coverage
• Lua: the 3rd party extensions (BTW not working for many years) are obsolete in 5.4 and removed
