rigol-ds: Add initial Rigol MSO5000 support.

This adds basic support for the Rigol MSO5000 series. It has
the same problems as the DS4000 series: Live capture provides
one digital channel per byte. Buffered memory returns the data
compressed (one byte has 8 digital channels), but the banks are
read separately. It's not possible to read uint16.
