This function compute the scaled log-ratios from raw probe intensities, as done by Nimblegen for scaling of ChIP-chip data.

Nimblegen provides scaled log-ratios as normalized values for the probes. log.ratio = log2(R)-log2(G) scaled.ratio = log.ratio - tukey.biweight(log.ratio)

Return an `MAList`

, with the M slot of the list holding the
scaled log ratios.
