Calculate QFE pressure to remote point using HP-42S calc

//Calculate QFE pressure to remote point using HP-42S programmable calculator!
//P0=QFE at respawn point, in hPa!
//T=temp at respawn point, in Celsius.
//H0=Ground elevation (ASL) at respawn, in meters.
//H1=Ground elevation (ASL) at target, in meters.
//Prints answer into X registry! in hPa!
//Very simple and basic code with low effort ;)
//Copyleft! Fell free to use as you want!
//HOWTO enter data: enter P0 then press R/S (and not ENTER) button on calculator, then enter T and press R/S and so on...
//Put all those shit below in https://www.swissmicros.com/dm42/decoder/index.php to make *.raw file from the code
