Use fast static array for default param

[PabstMirror]

Minor performance improvment from #503

AAA = {
    params [["_hash", [] call CBA_fnc_hashCreate, [[]]], "_key"];
    _key in (_hash select 1); 
};
BBB = {
    params [["_hash", [[], []], [[]]], "_key"];
    _key in (_hash select 1); 
};
hash = ["#CBA_HASH#",["A","B","C","D","E"],[1,2,3,4,5],nil];

return = [hash, "A"] call AAA;
return = [hash, "B"] call AAA;
return = [hash, "C"] call AAA;
return = [hash, "D"] call AAA;
return = [hash, "E"] call AAA;
return = [hash, "F"] call AAA;
return = [hash, "G"] call AAA;
return = [hash, "H"] call AAA;
return = [hash, "I"] call AAA;
return = [hash, "J"] call AAA;
// 0.167224 ms

return = [hash, "A"] call BBB;
return = [hash, "B"] call BBB;
return = [hash, "C"] call BBB;
return = [hash, "D"] call BBB;
return = [hash, "E"] call BBB;
return = [hash, "F"] call BBB;
return = [hash, "G"] call BBB;
return = [hash, "H"] call BBB;
return = [hash, "I"] call BBB;
return = [hash, "J"] call BBB;
// 0.0507 ms

Yeah. This "dummy hash" should be good enough for this.
