Imageize invisible character examples

[aphillips]

See: #113 (comment)

We need to add images for invisible characters in character template entries used in specdev because:

"This dog food is yummy" 🐶

@r12a could you make the images? I'll make a list of what we need.

Characters needed:

200F
200E
0009
000A
000B
000C
000D
0020
0085
00A0
1680
2000-200A
2028
2029
202F
205F
3000
FEFF
007F

You can find the images as follows: https://r12a.github.io/c/<block_name>/large/.png

eg. https://r12a.github.io/c/General_Punctuation/large/200F.png

The block name should be exactly as used in Unicode, including caps, and _ for spaces.

Just drag the result from the browser to the images directory.

Alternatively, you can just bring up each character on UniView and drag the (large) image to the directory. Eg.
https://r12a.github.io/uniview/?char=000C
