Avoid unpacking fields not required in requests

if bitmap indicates presence of field that we are not interested in , we should be able to not define them in the packager and the presence of them should not throw an exception (ArrayOutofbound) as the isofield (packagers) are not defined.

If a mux is not connected, the mod makes a message go through the following connected mux twice.

I have a bunch of muxes in my mux pool. 
<mux class="org.jpos.q2.iso.MUXPool" logger="Q2" name="xyz-mux">
 <muxes>xyz1-mux xyz2-mux xyz3-mux xyz4-mux</muxes>
