`text()` throws `TypeError` when giving a non-string value to it's `s` parameter
```python
pyxel.text(50, 50, pyxel.frame_count, 1)
```
Causes:
```shell
TypeError: argument 's': 'int' object cannot be converted to 'PyString'
```

Works fine if you explicitly convert integer/non-string values to a string using `str()`:
```python
pyxel.text(50, 50, str(pyxel.frame_count), 1)
```

Would it be possible for `text()` to behave similarly to `print()` and convert all arguments to strings where necessary.
