This PR adds everything that's needed on the segatools side to add E-Money support regarding Thinca authentication cards. I've also included set-up documentation (with a network side bonus which was as far as I could figure out so far, but I'm pretty certain no more changes to segatools will be needed) Due to the nature of a custom protcol called TCAP that Thinca uses for networking (see docs), I can't fully test that everything works as I haven't yet bothered to figure that protocol out. Tested with both APMv3 and FGO.  Reviewed-on: TeamTofuShop/segatools#35 Co-authored-by: Haruka <haruka@noreply.gitea.tendokyu.moe> Co-committed-by: Haruka <haruka@noreply.gitea.tendokyu.moe>
