Update: Utilize the state.flag to allow for fss read to not fail out on invalid UTF-8 code sequence and fix naming problems.

One of the original goals of the FLL project is to achieve fail-through functionality.
Knowing that this is a lot of work, I have ignored a lot of situations where I can implement fail-through and simply performed fail-out or fail-over.

With the upcoming stable release, I believe that this must handle bad data files.
This adds the option to conditionally change the behavior between fail-through and fail-out for the fss read functions and related for invalid UTF-8 code sequences.
The default behavior is now changed from fail-out to fail-through.

This took longer than I hoped.
I will need to do additional reviewing of this code before the stable release is ready.
I also realized that I need to support raw printing of data in the fss read functions as well (and that means changing the existing -r/--raw parameter).

This also fixes the following naming problems:
- fl_fss_apply_delimit() should be f_fss_apply_delimit().
- fl_fss_apply_delimit_between() should be fl_fss_apply_delimit_between().
