Subject: stm32/dac: Add buffering argument to constructor and init() method.

This can be used to select the output buffer behaviour of the DAC.  The
default values are chosen to retain backwards compatibility with existing
behaviour.

Thanks to @peterhinch for the initial idea to add this feature.
