rpici 9cca066ee8 Fix bug in test_tiff.cpp 
The big endian data in the tiff_sample_data array was never being tested.  This could be observed by e.g. changing the 9th byte in the big endian data from 0xde to something that should fail the test, e.g. 0xdd, and the test would still pass even though it should fail.

Ilari Venäläinen e6c41f0de6 Merge pull request #12989 from venalil:fix_thresholded_tiff_read 
* Fix reading of black-and-white (thresholded) TIFF images

I recently updated my local OpenCV version to 3.4.3 and found out that
I could not read my TIFF images related to my project. After debugging I
found out that there has been some static analysis fixes made
that accidentally have broken reading those black-and-white TIFF images.

Commit hash in which reading of mentioned TIFF images has been broken:
cbb1e867e5

Basically the fix is to revert back to the same functionality that has been there before,
when black-and-white images are read bpp (bitspersample) is 1.
Without the case 1: this TiffDecoder::readHeader() function always return false.

* Added type and default error message

* Added stdexcept include

* Use CV_Error instead of throw std::runtime_error

* imgcodecs(test): add TIFF B/W decoding tests
