delphi-utils dual-year geocoding files are not being exported in the package
While testing the jhu indicator on staging I discovered that it doesn't actually run:

```
[indicators@app-mono-dev-01 jhu]$ env/bin/python -m delphi_jhu
Traceback (most recent call last):

```

However I couldn't replicate it in my dev environment until I swapped the editable-install command used by `make test` for the uneditable-install command used by [build-and-package.sh](https://github.com/cmu-delphi/covidcast-indicators/blob/main/jenkins/build-and-package.sh).

Looks like we didn't update the package spec when we added in the 2010/2020 year split:

https://github.com/cmu-delphi/covidcast-indicators/blob/0bbcc1f91357318f2598d77c0a22bbe8fe0e02e8/_delphi_utils_python/setup.py#L43

CI didn't catch it because it always uses `pip install -e` 😭 , and it hasn't shown up as an error in production because Jenkins hasn't actually been deploying releases for quite some time. Thankfully Jenkins is fixed now, but we should:

- [ ] Fix the package spec (I'll take this)
- [x] #1443
