[BioC] Cel processing question

[bmb at bmbolstad.com]

The most recent change was from binary XDA format to binary COMMAND
CONSOLE (aka CALVIN) format. In any case affyio (which is giving the back
end of things like affy's ReadAffy()) supports reading this format, and
interchangably mixing it with the previous formats.

The tools in affxparser are presumably also able to do the same (since
it's built around affymetrix own file sdk).
