movingpandas/qgis-trajectools: v2.7

Changelog

This release brings multiple usability enhancements:

• Added proper datetime fields in output layers (instead of previous string type fields). This enables us to directly use the output with e.g. the Temporal Controller.
• Made trajectory ID field optional (for input layers with only a single moving object), fixes #37
• Improved help texts explaining trajectory ID and timestamp fields, fixes #35
• Drop potential extraneous geometry columns from attribute table, fixes #44
• Show better error message when NULL values cause parallel processing error, see #93
