You cannot modify a channel name because the ChannelList object keeps
them sorted. If you wish to rename a channel within a list, you must
delete it and reinsert it with the new name, or else assemble a
completely new ChannelList containing the channels the way you want.
You may find the source of the multiview utility instructive:
https://github.com/openexr/openexr/blob/master/OpenEXR/exrmultiview/makeMultiView.cpp
That reads in channels from the input(s) and writes them out with
different names.
You could drop a channel from the output file by making these two lines
conditional:
header.channels().insert(outChanName, inChannel);
and
outFb.insert(outChanName,image.channel(outChanName).slice());

In the ChannelList::Iterator and ChannelList::ConsIterator name() is
being defined as a const char * name () const, which means I can't
change the name. Is there anyway around this? I just want to be able
to change the channel name. I tried converting name into a string then
back into a const char * which works, but I have significant data loss
and the pixels no longer show up in the image.
