             Allow a 'file receive' packet which can request Espruino sends a file as binary packets (also fix files not being closed if transmission fails)
             Fix parsing of semicolons in DO with a statement: `do print(a);while(a--);`
             In SAVE_ON_FLASH builds (Microbit 1) remove getSerial, Math.LN*/LOG*SQRT* constants, passwords, Serial/I2C/SPI.find, Date.toUTCString

      2v24 : Bangle.js2: Add 'Bangle.touchRd()', 'Bangle.touchWr()'
             Bangle.js2: After Bangle.showTestScreen, put Bangle.js into a hard off state (not soft off)
