UZN support broken

[charlesw]

After upgrading to Tesseract 5.0 (see #579) the uzn test, CanParseUznFile, is failing with the following error:

  Expected string length 21 but was 33. Strings differ at index 5.
  Expected: "This is another test\n"
  But was:  "This s:h:}s:s as::tott;setr tESt\n"

Confirmed that I get the same result when using tesseract.exe so nothing to do with wrapper.

In case it helps anyone else, UZN support was broken in Tesseract 5.0 tesseract-ocr/tesseract#3837
That is why it doesn't work in this package.

Although this package claims to be on version 5.2.0 of Tesseract, it is not. Evidence provided by this issue #667 in addition to the fact that UZN support is broken in this package.

I can confirm that UZN support is working after locally upgrading Tesseract DLLs to 5.4.0.
