306 refactor data generators

[JanTeichertKluge]

All tests passed, except [RDD, not tested at all, not changed] and one test for DID:

> agg_weights[selected_unique_e_values >= 0] = 1 / np.sum(selected_unique_e_values >= 0) E numpy.core._exceptions._UFuncInputCastingError: Cannot cast ufunc 'greater_equal' input 0 from dtype('<m8[M]') to dtype('<m8') with casting rule 'same_kind' doubleml\did\utils\_aggregation.py:203: UFuncTypeError

doubleml/double_ml.py:1170

• The example code block formatting appears to concatenate two import statements on one line; please split them into separate lines to ensure proper formatting in documentation.

>>> import numpy as np        >>> import doubleml as dml

doubleml/double_ml.py:1286

• The code snippet delimiter and the following command are merged on one line; adjust the formatting to ensure each command is on a separate line for clarity.

--------        >>> import numpy as np

.github/ISSUE_TEMPLATE/bug_report.yml:26

• The code block opening in the issue template is misformatted due to extra spacing; ensure the markdown syntax for code blocks is correctly placed on its own line.

Please provide a short reproducible code snippet. Example:        ```python

Consider using the logical 'or' operator instead of the bitwise '|' for scalar comparisons to improve code clarity (e.g., 'if beta_a == 0 or gamma_a == 0:').

Suggested change

	if (beta_a == 0) | (gamma_a == 0):
	if (beta_a == 0) or (gamma_a == 0):
