ZI backend also configures instruments

Based on previous version of the qcompile function, the ZI-backend also includes configuration of the hardware. Recently, we have made the separation between the compilation (which generates files that describe how to execute a program) and the execution of the program rigid.

We consider preparing/configuring the hardware not as part of the compilation step but as part of the execution step. This also relates to #66 (closed) !70 (merged) .

We should tackle this as part of #87 (closed).
