  1. applet..spi_master: add delay commands. 

    These can be very useful if the SPI device requires specific timings;
in particular, for small delays (e.g. 10 us between commands) it is
much more efficient to implement these as subtarget commands than it
would be to wait on the host.

The synchronize method is useful for e.g. the following pattern:

  await spi_iface.write(...)
  await spi_iface.delay_ms(...)
  await device.write_register(...)

or in other words, in any case that SPI delays should have a defined
phase relationship to any other actions.
