Alexander Couzens 63a61bfdaf Add osmo_apdu_segment_in2() to ensure correct parsing of GP GET DATA
osmo_apdu_segment_in() doesn't have the context of the previous APDU,
for nearly all calls this is fine, except for GP GET DATA, which can be
a case 2 or case 4 APDU.
GP GET DATA defines the Le field as 0x00 which is used by osmo_apdu_segment_in
to detect if it is a case 2 or case 4.
However a card can respond with the SW 6cXX, which means the previous
command must be resend with a Le field XX, which got misinterpreted by
the osmo_apdu_segment_in() as a case 4 resulting in a timeout waiting for
more data.

Modem <-> Card
81cadf2000 ->
 <- 6c0b
81cadf200b ->
 -- Simtrace waits for more data because it wrongly decodes it as APDU case 4
    instead of case 2.
