US CPI Data for FRAX

[bryanjowers]

Provide the US CPI data from BLS released every month: https://www.bls.gov/news.release/cpi.nr0.htm

Docs/Resources:

The solution intended here for a node with an adapter that queries the data every month and write data on-chain for the series (each series has a unique series_id) detailed here:

https://www.bls.gov/feed/bls_latest.rss

For instance, for the headline print for "All items, U.S. city average, all urban consumers, 1982-84=100, 1-month percent change, seasonally adjusted" (the quoted CPI by media), data can be retrieved through the following GET request:

GET https://api.bls.gov/publicAPI/v2/timeseries/data/CUSR0000SA0

the adapter should check if current month data is available add only the newly added monthly data when available.

The schedule of releases of the data is available here: https://www.bls.gov/schedule/news_release/cpi.htm

All Series require the headline figure and the composition. Priority#1 to the headline figure ("seriesID": "CUSR0000SA0").

Requirements / Workflow

Requests for each series by date (month+year) should enable retieving the figure available

By default, a request should return the latest available month and figure

Additionally, the adapter could be enahnced by calculating the monthly and yoy increases/decreases for each series. by convention, the change %s are rounded to 1 decimal place.
