The builder is now more or less working as expected, but features are both missing and broken, which is expected.

Now more work is needed for the GMF file and the toml input file.
Now you can set the series to be referring to columns. After that you can fit those new series. This can be used to solve a = b + <random_var>
* Add more tests for the builder * Add more tests * Fix test
Fix GMF loading and saving with composed distributions
New operator similar to pd.is_null() or pl.is_null().
Ensure that computation with null is always null

This PR will be the main addition to metasyn 3.0. It is very far from ready. Given that the features are interlinked, this PR will unfortunately be quite big.
Planned features for this PR:
MetaFrame.fit_dataframe()method. This method would be growing too much and would have too much logic.MetaFrame.fit_dataframe()might still be offered for compatibility, but will lack some of the new features.-Removal of the
MetaConfig,VarSpecandDistSpecclasses. The functionality of these classes will be transferred to new classes.VarBuilderandMetaFrameBuilderclasses. These classes take the place of theMetaFrame.fit_dataframe()andMetaVar.fit()methods.ContinuousNormalDistribution(0, 1) + ContinuousUniformDistribution(0, 1). Fitters for these composed distributions will not be implemented. Depending on privacy considerations, fitters for a subset of the possible composed distributions might be implemented.TODO list:
Metaframe.fit_dataframe()method for backward compatibility.Fixes #434
