v3.2.0

There are a few interesting features in this release.

Many widgets have grown a `compact` reactive. If you set this to `True` then the widget will have a compact (borderless) style.

Reactives have a new `toggle_class` attribute, that toggles a TCSS classname according to the truthyness of its value. If that sounds complicated, it really isn't in practice. Let's see it in action:

```python
class MyWidget(Widget):
    compact = reactive(False, toggle_class="-textual-compact")
```

This adds a boolean attribute to the widget. If you set `compact=True` then it will add the class "-textual-compact". If you set `compact=False` it will remove the class. Simples.

We also have breakpoint support, so you can build UIs that adjust to the dimensions of the screen. This was always possible, but it was a pattern before. Now it is a first class feature. See the [breakpoints.py](https://github.com/Textualize/textual/blob/main/examples/breakpoints.py) example.

We also have two new pseudo classes: `:first-child` and `:last-child`, which have the same meaning as browser CSS. Contributed by @sponsfreixes

There is one potential breaking change. `RadioSet` now has a default width of 1fr, meaning they will take up the full available space. This makes RadioSet size like other widgets. If you want the original behavior, then set the width to "auto"
