multiple issues in kant_aufklaerung_1784-page-block-line-word_glyph about assets

@bertsky thanks for debugging.

1. The METS problem should be fixed.
2. That's right. There is no separate example for recording WORD in Page.
3. It's correct, all possibilities can occur. I'm sorry, glyphs only with coordinates based on squares do not represented reality.
4. All Unicode that refer to private areas should now be returned to "Standard" Unicode. In the case of ligatures there are now sometimes two characters (e.g. the ligature ch).
   But see: https://ocr-d.github.io/gt//trans_documentation/ocr_d_koordinationsgremium_codierung.html
5. Readme.md added and corrected.

Thanks @tboenig – that was fast!

Regarding 4, now I am puzzled: I still find ſt U+FB05 (ſt ligature from Unicode-Ll) in the new version. It does appear in the IMPACT table you referenced, but how is that relevant here? As far as I understand, our GT guidelines are different: ligatures are to be split up in all but transcription level 3 – but all the other GT files seem to be level 2. Which one is correct?

BTW, the table on ligatures in your guidelines has a typo: for the ſt ligature it says U+EADA instead of U+FB05.

@bertsky Thanks,

• the table on ligatures
  The error in the table is corrected.
• thank you again, for your reading carefully:
  The current version has to be corrected again, it would correspond to a Level 3 version then, I'm working on a correct version for Level 2 right now. This version will also be published.
