Correct table column widths

[ivyleavedtoadflax]

Column widths are calculated dynamically by https://github.com/MantisAI/hfie/blob/4cd9c4ea45188cae5169e358a69b81c89599c99f/hfie/utils.py#L4. It works by finding the longest entry for that column, and setting a column width based on that. This does not take into account the column header, meaning that we can end up with the column being less wide than the title, e.g.: (check the Revision column)

Name          State     Model      Revision   Url

It would be nice to amend add some functionality to https://github.com/MantisAI/hfie/blob/4cd9c4ea45188cae5169e358a69b81c89599c99f/hfie/utils.py#L14 to combine the header with the table data and calculate the width based on whatever is larger - the data or the header.
