fix: add TBC guild roster parser to avoid gender byte misalignment

Browse source 
TBC 2.4.3 SMSG_GUILD_ROSTER has the same rank structure as WotLK
(variable rankCount + goldLimit + bank tab permissions), but does NOT
include a gender byte per member (WotLK added it). Without this
override, TBC fell through to the WotLK parser which read a spurious
gender byte, causing every subsequent field in each member entry to
misalign.
