Update Latin-1 conversion table

[jkboyce]

Great list @Q726kbXuN that you compiled at glyph_counts.txt. Very interesting to see the frequency of unusual characters in NYT crosswords.

I dropped your list as-is into the code, but removed:

• Glyphs from u0000-u00ff inclusive, since these are valid Latin-1, and
• Emojis, since the encoder's replacements like \N{WINKING FACE} are as good as anything I could come up with.

So this is apparently every non-Latin-1, non-emoji character ever used in a NYT puzzle. A value of 'None' in the table causes the encoder to insert its own replacement. I put in conversions where I could think of something decent, but clearly this is more art than science so please feel free to edit. :)

Nice, thanks a ton for the work here, I'll (or anyone can, feel free!) to try and clean it up over time, but for now, it's a great start.
