Feature: provide string "except" functions.

The FSS Read functions utilize matching and printing on potentially delimited data.
If the delimits are not applied, then the matches and prints will be incorrect.
To avoid this, it seems that I need some way to not print the delimited data.

Provide "except" functions that accept and "except" array of strings representing locations within some string that are to be ignored.
The printing functions and comparison functions now have "except" equivalents.

The level_1 fl_print project appears outdated and needed updating anyway.
Restructure this project to use the private function practice, hopefully reducing the code size (and ideally binary size).
The "_string" part can be removed from the fl_print function names.
The parameter checks are loosened and now more closely match the approaches used in level_0 f_print.
