The good thing about safedec is that it may still decode ASN1
even if there is a mismatch between the expected tag (self.ASN1_tag)
and the actual tag; the decoded ASN1 object will simply be put
into an ASN1_BADTAG object. However, safedec prevents the raising of
exceptions needed for ASN1F_optional processing.
Thus we use 'flexible_tag', which should be False with ASN1F_optional.
Regarding other fields, we might need to know whether encoding went
as expected or not. Noticeably, input methods from cert.py expect
certain exceptions to be raised. Hence default flexible_tag is False.

ASN1F_SEQUENCE behaves transparently, with nested ASN1_objects being
dissected one by one. Because we use obj.dissect (see loop below)
instead of obj.m2i (as we trust dissect to do the appropriate set_vals)
we do not directly retrieve the list of nested objects.
Thus m2i returns an empty list (along with the proper remainder).
It is discarded by dissect() and should not be missed elsewhere.
