Add __repr__ for capstone.CsInsn (#1625)

* Add __repr__ for capstone.CsInsn

Currently, a `print(instruction)` displays a not very useful string like `<capstone.CsInsn object at 0x7f3759d88128>`.

This PR enhances adds a `__repr__` magic method to the `capstone.CsInsn` class so it displays as follows:
```
<cs.CsInsn: address=0x5555555545fa, size=1, mnemonic=push, op_str=rbp>
```

* Update __init__.py
