imwrite: implement DisposalMethod option.
* __magick_read__.cc (F__magick_write__): set gifDisposeMethod() when
writing an image to implement the DisposalMethod option. Set all the
options in a single option rather than a loop per option.
(init_reverse_disposal_methods): new method to return a reversed std::map
of the disposal methods.
(init_disposal_methods): move up, to be closer to the new
init_reverse_disposal_methods()
* private/__imwrite__.m: input check for the new option DisposalMethod and
set its default.
* imwrite.m: document new option.
