Add types

Can you provide Typescript types to this package?

When running `mtc`, I get:

```
Could not find a declaration file for module '@micro-frame/marko/dist/components/micro-frame/index.marko'. '~/node_modules/@micro-frame/marko/dist/components/micro-frame/index.marko' implicitly has an 'any' type.
```

and then get a whole bunch of Typescript errors relating to `<micro-frame>`
