             STM32: Ensure we kick the WDT if auto kicking is enabled and in deep sleep (avoids having to to it manually and wait 30ms for USB to wake up/shut down)
             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--);`

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

 * `ESPR_NO_PROMISES` - Don't include promise-handling functions
 * `ESPR_NO_PRETOKENISE` - Don't include code to pretokenise functions marked with `"ram"` - code pretokenised in the IDE can still be executed
