v0.2.2

• Added optional starting_datetime argument to TimexLCA.build_timeline explicitly. Before, it was buried in *args, which were passed to the underlying graph traversal (#93)
• Allow multiple calls of build_timeline using the same TimexLCA object, e.g., using different starting_datetime (#94)
• Fixed unintuitive rounding down of timestamps in dynamic characterization. 2024-12-31 would have been rounded to 2024, whereas 2025 makes more sense here. Now we round to the nearest year (21fa55b)
