Add the option to ident muxes outside process aligned with the tab

As a user, I want to...

Currently, program ident the muxes outside process aligned to the keyword '<= '. It would be nice if program could fill with spaces, balancing right and left sides, until reaching the configured identation pattern for avoid marking some of them as wrong idented

Example Input:

m_axis_data_tlast <= '1' when cnt_samples = 0 else -- Generate tlast on the last dataword sent
                     '0';

Example Output:

m_axis_data_tlast   <=  '1' when cnt_samples = 0 else -- Generate tlast on the last dataword sent
                        '0';
