Shortcut for *-projection

This works

```python
from net.imagej.ops import Ops

projected = ij.op().create().img([ im.dimension(d) for d in [0,1] ])

# Create the op and run it
proj_op = ij.op().op("stats.max", im)
ij.op().transform().project(projected, im, proj_op, 2)
```

but this would be even easier!

```python
projected = ij.op().transform().project(im, "stats.max", 2)
```

Start from the existing transform().project API used in the explicit example and trace how the projection operation is created and invoked. The change is done when a shortcut accepts the image, operation name, and dimension as shown and returns the projected image; no test or source file is named in the issue.
