This function returns a bitmasked value showing which indicators are turned on. The 16-bit binary equivalent of
the returned value is the bitmask. The return value is a sum of set annunciators, based on the weighted value, as
shown in the following table.

testAnnunciators = display.getannunciators()
print(testAnnunciators)
rem = bit.bitand(testAnnunciators, 1024)
if rem > 0 then
print("REM is on")
else
print("REM is off")
end
REM indicator is turned on.
