Upgrading to version 3

[aidanhorn]

The purpose of this issue is to document what changes will be made to codebases when upgrading from version 2 of econdatar to version 3.

Column names in long data

Old name	New name
data_key	series_key
period	time_period
value	obs_value

When using Find & Replace, please use the regex value(?!s) to avoid replacing values_from inside pivot_wider(), or values in scale_color_manual() or scale_fill_manual().

The metadata item when the data are returned in a long (relational) format is now a list. The analyst should thus enclose the metadata item in as_tibble() in order to achieve the same tabular format as before.
