Better map handling

Improved handling of tags with maps for Aspen IP.21.

Fixed

• Allow tag search with tagname and description.
• Fix fetching of correct unit for tags with map.
• Fix fetching of correct description for tags with map.

v1.0.1

Fixed

• Fix FutureWarning regarding use of keep_tz=False in DateTimeIndex.to_series()

Rename and first release on PyPI

First release on PyPI as tagreader

Changed

• Rename from pyIMS to tagreader to avoid name collision on PyPI
• Move lots of tests to a separate private repository. Those tests need to be run on-site with functioning server connection to PI/IP.21 servers, and are currently handled in Azure Pipelines.

v0.2.0

Last release with name pyIMS.

This release should be the same as the pyIMS v0.2 tag on the Equinor internal GitLab.

Future releases will be made in the new name tagreader, and will hence break compatibility with previous releases.
