Fix: Tesseract 3.04 is sensitive to order of configuration commands
...
“txt hocr” is not acceptable and does not produce expected output .txt
while “hocr text” works fine, so switch the order everywhere.
Should fix #169

Turn on Tesseract 4 cache in test suite
...
Travis is too slow without it, and perhaps it’s overly paranoid to
never cache Tess4. Maybe nuke the cache occasionally to be safe…

Fix test suite breakage after sidecar feature added
...
Forgot to update tesseract spoofers to account for change in tesseract
parameters. Also the change to outputting multiple files in the collate
steps affected how ruffus passes information into downstream consumers
of those files.

Add documentation and test cases for —tesseract-config
...
This parameter has existed for along time but never really got any
attention.

tesseract caching: don't transcode tesseract's output, hash source file
...
For sanity's sake, deal with tesseract streams in binary without
transcoding (via universal_newlines, etc.). The only differences are
printing messages regarding spoofing.
Also hash the source file so that changes to the cache mechanism
invalidate old cache automatically. That is probably too aggressive,
but simple and safer than the previous approach.

Update tesseract spoofing to cache orientation and script detection checks
...
No cache: 269 s
With cache: 144 s
test_oversample[tesseract] now fails, all others good

Adjust test cases to use cache and noop more effectively
...
This reduces total execution time to 164s on my machine, down from
about double that.
