conflict with zlib-1.2.11

[frankrw3]

The new zlib-1.2.11 has a new function that is called uncompress2 that conflicts with the one in cdriso.c line 916 and line 995.

cdriso.c:916:static int uncompress2(void *out, unsigned long *out_size, void *in, unsigned long in_size)
cdriso.c:995: ret = uncompress2(compr_img->buff_raw[0], &cdbuffer_size, compr_img->buff_compressed, size);

to resolve this conflict I renamed the uncompress2 in the cdriso.c file.
