Find a matching or allocate a new rs control structure, for fields with non-canonical representation
struct rs_control * init_rs_non_canonical(int symsize, int (*gffunc) (int), int fcr, int prim, int nroots);
symsize
the symbol size (number of bits)
gffunc
pointer to function to generate the next field element, or the multiplicative identity element if given 0. Used instead of gfpoly if gfpoly is 0
fcr
the first consecutive root of the rs code generator polynomial in index form
prim
primitive element to generate polynomial roots
nroots
RS code generator polynomial degree (number of roots)
