Support for time series data

[marinaevers]

Add initial support for uncertain time series. This includes a class building on the distribution class but also contains the time steps. Additionally, meaningful plots are required, for example, similar to this paper: https://doi.org/10.1109/TVCG.2024.3364388

The basic interface is created in the branch time_series. What still needs to be done before merging to main:

• [ ] Implement time series plot (see #30)
• [ ] Implement correlation length plot (see #31)
• [ ] Check and create example
• [ ] Update documentation
