Add base class for metrics in metrics/base.py

[sweep-ai]

Description

This PR adds a base class for metrics in the metrics/base.py file. The base class, BaseMetric, provides a foundation for implementing various metrics that can evaluate the similarity between synthetic and real datasets.

Summary

• Removed the pass statement from the metrics/base.py file.
• Imported the ABC and abstractmethod from the abc module.
• Created a new class named BaseMetric that inherits from ABC.
• Defined an __init__ method in the BaseMetric class to store the real_data and synthetic_data as instance variables.
• Defined an abstract method named calculate in the BaseMetric class to calculate the metric. This method will be implemented in each subclass.
• Defined a method named validate_datasets in the BaseMetric class to validate the input datasets. Currently, this method does not perform any validation.

Please review and merge this PR. Thank you!

Fixes #3.

There are a lot of errors. This is likely due to a small parsing issue or a missing import with the files changed in the PR.

This is likely a linting or type-checking issue with the source code. Update the code changed by the PR. Don't modify the existing tests.

I'm getting the same errors 3 times in a row, so I will stop working on fixing this PR.
