Subject: Teach the ASN.1 compiler the no_ok_wrapper option

Add the no_ok_wrapper option so that the generated M:encode/2 and
M:decode/2 functions will not wrap a successful return value in an
{ok,...} tuple. Errors will cause exceptions.

Eliminating the wrapping tuple allows simpler nesting of calls.
