:sparkles: enhance `dataset.read_table(...)` method

[Marigold]

Historically, we've been using function dataset["my_table"] to access table from a dataset. Recently, a new helper method dataset.read_table(reset_index: bool) has been added that lets us read the table with reset index which is significantly faster for large dimensional datasets.

We could add more functionality to read_table and make it de facto standard to read tables. These could be:

• Retype all columns to "standard" types (e.g. uint8 -> int64, Float16 -> float64) and categorical to string type
• underscore column names etc. (see .format method)
• etc.
