Fix 217: Merge function for Qasm Modules

[arunjmoorthy]

Summary of changes

Fixes issue 217 by adding a merge function, so two QasmModule objects can be combined into one. The merge function unrolls both modules and creates a single qubit declaration. This function appends the second QasmModule object with the correct index offsets and returns a Qasm3Module.

The test_merge.py file is added, which has a few examples of merging two modules, using the merge function.
