Support FIGlet layoutmodes and smushing

[OliverRC]

It looks like FigletText currently supports a rudimentary implementation of the FIGlet renderer.
A missing feature would be that of the layoutmodes / smushing.

These must "smush" the text together for a slightly more attractive aesthetic.
Text examples using "standard.flf" for example look like this:

    _    ____   ____ ____  _____ _____ ____ 
   / \  | __ ) / ___|  _ \| ____|  ___/ ___|
  / _ \ |  _ \| |   | | | |  _| | |_ | |  _ 
 / ___ \| |_) | |___| |_| | |___|  _|| |_| |
/_/   \_\____/ \____|____/|_____|_|   \____|
                                            

       _             _       __       
  __ _| |__   ___ __| | ___ / _| __ _ 
 / _` | '_ \ / __/ _` |/ _ \ |_ / _` |
| (_| | |_) | (_| (_| |  __/  _| (_| |
 \__,_|_.__/ \___\__,_|\___|_|  \__, |
                                |___/ 

 _ ____  _____ _  _  ____   __ _____ 
/ |___ \|___ /| || || ___| / /|___  |
| | __) | |_ \| || ||___ \| '_ \ / / 
| |/ __/ ___) |__   _|__) | (_) / /  
|_|_____|____/   |_||____/ \___/_/

However, they land up looking like this

  ____                   _             _      ____                                               _                 
 |  _ \    ___    _ __  | |_    __ _  | |    / ___|   ___    _ __ ___    _ __     __ _   _ __   (_)   ___    _ __  
 | |_) |  / _ \  | '__| | __|  / _` | | |   | |      / _ \  | '_ ` _ \  | '_ \   / _` | | '_ \  | |  / _ \  | '_ \ 
 |  __/  | (_) | | |    | |_  | (_| | | |   | |___  | (_) | | | | | | | | |_) | | (_| | | | | | | | | (_) | | | | |
 |_|      \___/  |_|     \__|  \__,_| |_|    \____|  \___/  |_| |_| |_| | .__/   \__,_| |_| |_| |_|  \___/  |_| |_|
                                                                        |_|                                        

When rendered using:

var font = FigletFont.Load("standard.flf");
AnsiConsole.Write(new FigletText(font, "Portal Companion")

The man page describes:
http://www.figlet.org/figlet-man.html

-m layoutmode
Specifies an explicit layoutmode between 1 and 63. Smushmodes
are explained in figfont.txt, which also provides complete
information on the format of a FIGlet font.

From details of the layout modes can be found in the figlet.txt
