docs: Get the value of a given bitfield.
          :param fmt: format-string for the bitfield being read, e.g. 'u8' for
              an unsigned 8-bit integer.
          :param offset: offset (in number of bits). If prefixed with a
              '#', this is an offset multiplier, e.g. given the arguments
              fmt='u8', offset='#2', the offset will be 16.
          :returns: a :py:class:`BitFieldOperation` instance.
