jpx_metanode::get_numlist_codestreams

Returns NULL unless get_numlist_info returned true. In that event, the function returns a pointer to the internal array of codestream indices which are recorded in the number list. This could still be NULL, if there are no codestream indices referenced by the number list. The number of entries in the array may be found using the get_numlist_info function.

Note that all codestream indices start from 0 for the first codestream in the JPX file.
