feat(lua): Add getSourceValue (#2316)

Browse Source 
* Moved getFieldInfo and getValue up right after related functions

* Modified getValue to return a valid status, so Lua can see if it got zero because of invalid source id

* Added new getSourceValue Lua function per Issue #781
Also added alias getSourceInfo for getFieldInfo

* Updated according to comment https://github.com/EdgeTX/edgetx/pull/2175#issuecomment-1245605114

* Replaced isFresh() by !isOld() as requested in https://github.com/EdgeTX/edgetx/pull/2316#issuecomment-1246759370

* Clean up `lua_pushtablenil` - tables cannot hold nil values

* Changed isFresh() to !isOld() ... AGAIN

* Return both `!isOld()` and `isFresh()`

* Return nil for all values if the item does not exist

* Return 0 instead of pushing three nil values

* Update documentation
