Jan Polák dea0815199 Small imencode documentation improvement 
It was previously not clear that the extension should include the period, [and I am not the only person that encountered this problem](https://stackoverflow.com/questions/4254460/opencv-could-not-find-encoder-for-the-specified-extension).

I assume that this is true for all supported extensions, but I haven't checked the source.

Pierre Chatelier 6390b50d6e Merge pull request #21701 from chacha21:tiff_10_12_14 
Add 10-12-14bit (integer) TIFF decoding support

* Add 12bit (integer) TIFF decoding support

An (slow) unpacking step is inserted when the native bpp is not equal to the dst_bpp

Currently, I do not know if there can be several packing flavours in TIFF data.

* added tests

* move sample files to opencv_extra

* added 10b and 14b unpacking

* fix compilation for non MSVC compilers by using more standard typedefs

* yet another typdef usage change to fix buildbot Mac compilation

* fixed unpacking of partial packets

* fixed warnings returned by buildbot

* modifications as suggested by reviewer

nickjackolson 79d4e865fe Add warning message to imread() 
Add a warning message using CV_LOG__WARNING().
This way api behaviour is preserved. Outputs are
the same but user gets an extra warning in case
fopen() fails to access image file for some reason.
This would help new users and also debugging
complex apps which use imread()
