Publish packages to NPM

We are going to try publishing under the @apollo-annotation scope. Things to keep in mind:

We'll have to change the "name" of our packages that we publish, e.g. jbrowse-plugin-apollo will become @apollo-annotation/jbrowse-plugin-apollo
Start with publishing @apollo-annotation/jbrowse-plugin-apollo and any of its dependencies.
We'll have to remove "private": true" from the package.json of the packages we publish and replace it with
```
{
"publishConfig": {
"access": "public"
}
}
```
We should probably match all of our published package versions, at least to start. I think 0.1.0 would be a good version for now.
Make sure to use a tag when publishing (e.g. "beta") for now so we don't use the default "latest" tag until we're ready for a more official release. https://docs.npmjs.com/adding-dist-tags-to-packages
It would probably be good to add some sort of single command to publish all the packages, maybe using yarn workspaces foreach
There might also be some good tips here: https://yarnpkg.com/features/release-workflow
