src/dvbpsi.h: set i_last_section_number when adding a new section to the end of the list

The function dvbpsi_decoder_psi_section_add() never set p_decoder::i_last_section_number when
adding a new section at the end of the list. This was left to the decoder implementations. However
the correct action would have been to set p_decoder::i_last_section_number in dvbpsi_decoder_psi_section_add().

(cherry picked from commit 7e9f4ed39444c84679b1135684ec2aa4f39e476c)

SCTE35 / CUEI Descriptor parsing bug. Descriptor lengths of one byte fail to parse, instead returning null.

The Spec from 2004 to 2016 shows the descriptor payload has never been
more than a single byte.
See SCTE 35 2016 Page 19 Table 2 (Section 8.2).

Correct the length validation check, and reject any descriptor that
IS NOT one byte long, as per the spec.
