IAMconsortium/pyam: Release v0.7.0

Release v0.7.0 Highlights

• Add new features for aggregating and downscaling timeseries data.
• Update the plotting library for compatibility with the latest matplotlib release.
• Refactor the feature to read data directly from an IIASA scenario database API.
• Migrate the continuous-integration (CI) infrastructure from Travis & Appveyor to GitHub Actions and use CodeCov.io instead of coveralls.io for test coverage metrics.

PR #413 changed the return type of pyam.read_iiasa() and pyam.iiasa.Connection.query() to an IamDataFrame (instead of a pandas.DataFrame) and loads meta-indicators by default.

Also, the following functions were deprecated for package consistency:

• index() replaces scenario_list() for an overview of all scenarios
• meta_columns (attribute) replaces available_metadata()
• meta() replaces metadata()

PR #402 changed the default behaviour of as_pandas() to include all columns of meta in the returned dataframe, or only merge columns given by the renamed argument meta_cols. The feature to discover meta-columns from a dictionary was split out into a utility function pyam.plotting.mpl_args_to_meta_cols().
