create iterator over cpl_frameset

Parameters

frames	frames to iterate
flags	flags of iterator
naxes	number axis to iterate
axes	axes iteration order
offsets	offsets in axes (NULL for no offset)
strides	strides in axes (NULL for stride 1)
dims	dimensions of axes (NULL for dimensions of data)

Create iterator over uniform frameset and extensions. Treats data as [nframes,next,nx,ny,nz] dimensional array and iterates over some axis of this data. Currently only supports iterating over frame and extension axis and returning 2d images. E.g. create iterator iterating first over the frames beginning at offset 0 and stride 1, then over the extensions beginning at offset 2 (primary is offset 0) with stride 2. It returns a cpl_image in each iteration which is owned by the caller. The dimensions are defined by the data in the frames:

it = hdrl_frameiter_new(frames, 2, (intptr_t[]){HDRL_FRAMEITER_AXIS_FRAME, HDRL_FRAMEITER_AXIS_EXT}, (intptr_t[]){0, 2}, (intptr_t[]){1, 2}, NULL), for (cpl_image * h = hdrl_iter_next(it); h != NULL; h = hdrl_iter_next(it)) { cpl_image_delete(h); } hdrl_iter_delete(it);
