In general, I think it would be great to publish our framework to conda, such that we can directly support environments without `geopandas` pre-installed

In #609 we agreed on moving out the assign_pfs_to_sps functionality of generate_triplegs function and only support case 1. These id assignments are related to #251

The changes in #393 simplify the logic for the code but significantly affect the performance. This is because the previous `change_flag` splits all rows at each iteration, while the current...

Our [location_generation](https://github.com/mie-lab/trackintel/blob/4babae92f8d26abf92d80f8b19fd530f2cb4e7e2/trackintel/preprocessing/staypoints.py#L12) relies on the DBSCAN algorithm and enables the generation of `user-` and `dataset-level` locations. Locations are generated from `core` points from the DBSCAN results. When the input `epsilon`...

The current `read` functions in `io` would proceed without an error or warning when not providing a `crs` as input; the resulting trackintel class object thus has no `crs` set...

Change default behaviour of merge_staypoint()

The function accepts sp and tpls as input. But if an `empty` or `pd.DataFrame` or `gpd.Geodataframe` tpls is given, this [line](https://github.com/mie-lab/trackintel/blob/136ad8b045bcd1e50258a4ff7371d2d9fb86b904/trackintel/preprocessing/staypoints.py#L273) will raise a warning as tpls has no crs....
