[BioC] Generating .CHP files from .CEL files

CEL files contain the raw data. That should be on GEO. With CEL
files and a complete verbatim description/code of the analysis one can
ideally regenerate the results.
CHP files contain processed signals/summarized signals/parameter
estimates - not raw data. CHP files are typically generated by
Affymetrix software tools only. If your analysis was using, say,
Bioconductor tools, you never generated CHP files. If so, it doesn't
make sense for GEO to ask for them.
