Feature: Function Dataset

Description

This pr introduces a generalized way to create datasets from functions.

Which issue does this PR tackle?

Currently each dataset created from a function has its own implementation.
Creating benchmarks in which these implementations are adjusted is hard and requires much time.
- When evaluating the distribution of parameter samples
- When evaluating the distribution of space samples
- When evaluating the density of parameter samples
- When evaluating the density of space samples
- When evaluating the effect of discretization invariance
- When evaluating the effect of variing number of sensors

How does it solve the problem?

Implements Function, ParameterizedFunction, FunctionSpace, SampledFunctionSpace and a FunctionOperatorDataset class with multiple factories for creation.
The sampling of the parameterized functions and space is handled by the samplers defined in the discrete module and can be swapped out to create different properties within a dataset.
Factories make for easy use without having to think about concrete samplers.
Facilitates the creation of benchmarks listed in the section above.

How are the changes tested?

Closed this for now until I am able to rebase main with RegularGridSampler feature from #64 .
