resource: Add smart cropping
This commit `smart` as a new and default anchor in `Fill`.

So:

```html
{{ $image.Fill "200x200" }}
```

Is, with default configuration, the same as:

```html
{{ $image.Fill "200x200" "smart" }}
```

You can change this default in your `config.toml`:

```toml
[imaging]
[imaging]
resampleFilter = "box"

quality = 68

anchor = "Smart"
```

Fixes #4375
