feat(transparency): add ignore rules to config

This commit adds transparency_ignore_rules to the komorebi.json static
configuration format. Windows that match any rules given in this list
will not have transparency applied when they are unfocused.

For example, to ensure that a browser window is not made transparent
when the focused tab is a YouTube video:

```json
"transparency_ignore_rules": [
  {
    "kind": "Title",
    "id": "YouTube",
    "matching_strategy": "Contains"
  }
]
```
