tests/coding: add 11-bit Access Burst samples from a real phone
This change adds several soft-bit (-127 .. 127) sequences containing
EGPRS Packet Channel Request message (11-bit, payload only) sent by
an EGPRS capable phone, and captured on the BTS/PCU side using a
tool from the TRX Toolkit - trx_sniff.py.
As can be seen from the test output, none of decoded RA11 values
looks like a valid EGPRS Packet Channel Request message (see
table 11.2.5a.2 of 3GPP TS 44.060). All test sequences contain
the same message with several random bits:
< EGPRS Packet channel request message content > ::=
< Signalling : 110011 < RandomBits : bit (5) > >;
since the phone was trying to perform Attach Request. It seems
the bit order of decoded messages is somehow wrong.
