madevent eemumu generation fails (problems in dressed_lep)

Hi @oliviermattelaer the default madevent eemumu generation fails with the latest code

generate e+ e- > mu+ mu-
output madevent CODEGEN_test

This also fails for

output madevent CODEGEN_test --vector_size=16

[valassi]

As a workaround, I will just set dressed_lep=False, it seems to work

            if tuple(initial_states) in [([-11],[11]), ([11],[-11]), ([-13],[13]),([13],[-13])]:
                dressed_lep = True
            else:
                dressed_lep = False
            dressed_lep=False # workaround for https://github.com/oliviermattelaer/mg5amc_test/issues/6

Funny I do not reproduce that issue ....

ok I do now

[oliviermattelaer]

Ok the generation of the code is working now. Now the running of the normal madevent has issue if you do not set --vector_size due depending of the value in the run_card (the mc_grouped_subproc which should normally be supported without any --vector_size)

See #7

Thanks @oliviermattelaer I also confirm this one is fixed for me now

Sorry I spoke too early, eemumu generation still fails, but with a different error. I opened a new #10 (against revision 999).

This issue with dressed_lep however (#6 against revision 996) has indeed disappeared.
