Adjusted

[aheschl1]

I have added the capacity to query for "adjusted" tim series data.

For the client, this includes:

1. get_time_series_monthly_adjusted_full
2. get_time_series_weekly_adjusted_full
3. get_time_series_daily_adjusted_full
4. get_time_series_daily_adjusted

Only daily has the compact data.

Other changes that have occured include some visibility changes insode of TimeSeries that I have found useful. This is just changes from pub(crate) to pub in some places.

The addition of adjusted time series includes some major changes to parsing, and a little bit of repetitive code, which I am not sure how to avoid.

Test cases

Entry now has three extra Option fields. By default, these will be None if querying for a "non adjusted" time series.

does the failed "Test" check mean test cases didn't pass?? if so I must have messed up the merge

Tests are passing but there are other checks to ensure cargo clippy does not generate any warnings and cargo fmt --check passes.
