species value inflation adjustment data

[andybeet]

The function adjust_inflation used to pull a monthly inflation time series from a government website.

In the past there were issues pulling this data and the package changed to handle a data object that was bundled with the package. comlandr::deflate. This is hard to maintain and we need to revert back to the previous method.

Questions @gdepiper :

Is this still the correct url? : http://download.bls.gov/pub/time.series/wp/wp.data.3.ProcessedFoods
If so, how is the correct series_id determined? We were previously using WPU0223.

Apologies, I was on travel the first time you pinged me on this, and am on travel again this week. This series has been depricated. The new deflator to use is the GDP implicit price deflator, and can be found here: https://fred.stlouisfed.org/series/GDPDEF

Note that it is a quarterly, not monthly, deflator. I am back next week and can discuss further.
