[BUG] Error in function call with aliased qubit

[TheGupta2012]

Environment

• PyQASM version: 0.1.0
• Python version: 3.11.6
• Operating system: macOS 15.1.1

What happened?

Aliased qubit was not loaded as a function call argument -

In [1]: import pyqasm

In [2]: qasm_str = """
   ...: OPENQASM 3;
   ...: qubit[3] q;
   ...: 
   ...: def dummy(qubit[1] q_arg) -> bool { 
   ...:     h q_arg;
   ...:     return true;
   ...: }
   ...: 
   ...: for int i in [0:2]
   ...: {
   ...:    let new_q = q[i];
   ...:    dummy(new_q);
   ...: }
   ...: """
   ...: 
   ...: 
   ...: 
   ...: 

In [3]: module = pyqasm.loads(qasm_str)

In [4]: module.validate()
ERROR:root:Error at line 13, column 3 in QASM file

....
ValidationError: Expecting qubit argument for 'q_arg'. Qubit register 'new_q' not found for function 'dummy'

This should not happen and the actual qubit register i.e. q[i] should be propagated to the function call

Suggestions (Optional)

Most likely we need to check the alias map too while mapping formal quantum args to actual quantum args
