v3.35.0: EF.SMSP decoded editor (the full SMS-parameter form)

Browse Source 
TS 31.102 4.2.27 scope: alpha; TP-DA and TS-SCA with their own length
conventions (DA = digits, SCA = octets, 0 = default SMSC) and a TON
select; TP-PID; TP-DCS with TS 23.038 hints; the relative TP-VP with the
TS 23.040 ladder; a per-parameter "absent (the ME default applies)"
state.  Unchanged slots are copied verbatim (the live fixture's
DCS-absent 00 and present VP FF survive), alphanumeric TON-5 addresses
stay read-only, and every checked record is validated before any write.

Decoder fixes: the parameter-indicator bits were shifted (SCA on 5,
PID on 2, DCS on 3, VP on 4; the spec is DA/SCA/PID/DCS/VP on bits 1-5
with 6-8 reserved, 1 = absent), and the TP-DA length was read as octets
instead of digits (TS 23.040 9.1.2.5).

Live fixture: ffffffffffffffffffffffffffe9ffffffffffffffffffffffff07919733824009f0ffffffff0000ff
(SCA +79332804900, PID 00, DCS absent/00, VP FF) round-trips
byte-identically.

1022 Python + 1058 frontend green; simple-v468.
