Detailed Description

Implements the OP_CALL opcode for function calls in the VM.

This file handles the OP_CALL instruction, which calls a function with arguments.

Behavior:

• operand specifies number of arguments
• Pops args and function from stack
• Creates new frame with args in locals
• Sets IP to start of function

Error Handling:

• Exits with error if not enough args
• Exits if function isn't callable
