提供data-cache和data-domains支持

https://umami.is/docs/tracker-configuration

摘录自官方文档

data-cache
If you get a lot of pageviews from the same user, for example in a forum website, you can cache some data to improve the performance of the tracking script.

Note: This will use session storage so you may need to inform your users.

Usage:
```javascript

```

data-domains
If you want the tracker to only run on specific domains, you can add them to your tracker script. This is a comma delimited list of domain names. Helps if you are working in a staging/development environment.

Usage:
```javascript

```

No repository files or tests are named. Start by tracing how the plugin configures or emits the Umami tracking script, then compare it with the linked tracker-configuration documentation; done means both data-cache and data-domains are supported with the documented behavior.
