Add strict argument to audformat.utils.hash()

[hagenw]

Closes #447

Adds the strict argument to audformat.utils.hash(). If True it will take the order of rows and the names of index levels and columns into account. The returned hash is then identical to the one attached to parquet table files.

A hashing variant that takes into account the order of rows, name of columns and levels, and the data types was needed for calculating a hash for parquet tables as introduced in https://github.com/audeering/audformat/pull/419. Before, this was handled by a private method, independent of audformat.utils.hash().

include_order_and_names is verbose, but also slightly long as an argument name. strict might be a better choice?

I added a reference to #419 in the description and renamed the argument to strict, thanks for the suggestions.
