Supreeth Herle 95b4e8d4fa utils.py: Add helper method to parse ePDG Selection info TLV
ePDG selection information TLV data object is made of following elements:

ePDG Selection Information Tag '80' (1 Byte)
Length 5n Note
PLMN 1 (3 Bytes)
ePDG Priority (2 Bytes)
ePDG FQDN format '00' or '01' (1 Byte)
...

PLMN n
...

Note: The length is coded according to ISO/IEC 8825-1 [35]

Note 2: Inconsistency in spec: 3GPP TS 31.102 version 15.2.0 Release 15, 4.2.104

As per spec, Length field value is 5n, where n is number of PLMNs
But, each PLMN entry is made of PLMN (3 Bytes) + ePDG Priority (2 Bytes) + ePDG FQDN format (1 Byte)
Totalling to 6 Bytes, maybe Length should be 6n and not 5n
