v0.82.0

The highlight of this release is the new [keymap](https://textual.textualize.io/api/app/#textual.app.App.set_keymap) support, which enables dynamic configuration of keys -- so you can now provide a way for users of your app to customize key bindings.

Keymaps aren't documented beyond the API level at the moment. That will happen in a few releases. In the meantime, @darrenburns has written up this new feature (which he also implemented) on his blog. Check it out:
