=Description=
Returns whether or not the given friend code is valid. The following logic is used (everything is in little-endian byte order):
<code>
is_valid = friend_code != 0 &&
(u32)(friend_code >> 32) <= 127 &&
=Response=
[[FRDU:PrincipalIdToFriendCode]]((u32)(friend_code & 0xFFFFFFFF)) == friend_code
</code>
