Libify tdfonts_lib.js, creating tdfiglet.js (the front-end) 

Just split tdfonts_lib.js in half basically

tdfiglet.js is the "front-end" (e.g. for use with jsexec or ;exec sysop
command).

* tdfiglet.js - Synchronet JS conversion of tdfiglet.c
* Based on the C code by Unknown/Modified by The Draw
* Converted to Synchronet JS by Nelgin
*
* Note: This is a best-effort conversion based on the provided C code.
* Synchronet JS environment differences (like file I/O, binary data handling,
* and character encoding) may require adjustments.
* The C code's mmap and directory listing will be replaced with Synchronet JS equivalents.
* The iconv part for IBM437 to UTF-8 conversion will need a JavaScript equivalent,
* possibly a lookup table or relying on Synchronet's native encoding handling.
