bug: addressing issue in rust vm_consts getter

[enitrat]

when executing pythonic hints in rust, there's a small issue when accessing members of cairo structs:

eg

    %{
        if ids.err.value == 0:
            print(f"[CAIRO] OpEnd")
    %}

This should be equivalent to:
%{
if memory[ids.err.address_] == 0:
print(f"[CAIRO] OpEnd")
%}

But fails because it's not dereferencing the err because of Expected relocatable at address 1:25517
