Checked in a new version of the ASCA cleansis tool to remove hot and flickering pixels. This now works for other instruments with different numbers of CCD chips and image sizes. If the instrument has only one chip (as Swift XRT) then the chipcol parameter should be set to NONE.

One issue outstanding is that the number of chips is deduced from the TLMIN/MAX keywords of the chipcol column. If events have been selected from a subset of chips then cleansis will still try to work on all the chips containing no events. This doesn't produce a problem but does make the screen summary output a bit ugly.
