//essentially : get commandIndex and totalCommands, calculate offset of new command, copy command and update totalCommands
//use LDREX/STREX because this data may also be accessed by the GSP module and we don't want to break stuff
//(mostly, we could overwrite the buffer header with wrong data and make the GSP module reexecute old commands)
