Stitching Detailed Tutorial Improvements

* Add Vertical Wave Correction

The user has the possibility to pass "vert" as wave_correct parameter. However, in the code "cv.detail.WAVE_CORRECT_HORIZ" ist fixed. This change proposes changes so that the wave correction is done vertically if the user passes "vert" as wave_correct parameter. The variable "do_wave_correct" is replaced by None which is passed to the variable "wave_correct" if the user chooses "no" for wave correction.

* Correct fixed conf_thresh

According to the documentation, [cv.detail.leaveBiggestComponent](https://docs.opencv.org/4.5.1/d7/d74/group__stitching__rotation.html#ga855d2fccbcfc3b3477b34d415be5e786) takes features, the pairwise_matches and the conf_threshold as input.
In the tutorial, however, conf_threshold is fixed at 0.3 even though the user can pass conf_thresh as parameter which is 1 by default. Fixing this parameter at 0.3 causes the script to include images into the panorama which are not part of it.

* Error Message for SURF if not implemented

In OpenCV 4.5.1 

import cv2 as cv
cv.xfeatures2d_SURF.create

will not create an AttributeError, even if the function is excluded (no nonfree option)

In Line 305 (now 306) however ´finder = FEATURES_FIND_CHOICES[args.features]()´ will raise an 

error: OpenCV(4.5.1) ..\opencv_contrib\modules\xfeatures2d\src\surf.cpp:1029: error: (-213:The function/feature is not implemented) This algorithm is patented and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library in function 'cv::xfeatures2d::SURF::create'

So we should check with cv.xfeatures2d_SURF.create() correctly if SURF is available

* use avcodec_get_hw_frames_parameters; more robust fallback to SW codecs

* internal function hw_check_device() for device check/logging

* two separate tests for HW read and write

* image size 640x480 in encode test

* WITH_VA=ON (only .h headers used in OpenCV, no linkage dependency)

* exception on VP9 SW encoder?

* rebase master; refine info message

* videoio: fix FFmpeg standalone plugin build

* videoio(ffmpeg): eliminate MSVC build warnings

* address review comments

- remove parallel decoding by SW code path
- check PSNR against the original generated image

* videoio: minor fixes

* videoio(test): disable unsupported MSMF cases (SW and HW)

* videoio(test): update PSNR thresholds for HW acceleration read

* videoio(test): update debug messages

* "hw_acceleration" whitelisting parameter

* little optimization in test

* D3D11VA supports decoders, doesn't support encoders

* videoio(test): adjust PSNR threshold in write_read_position tests

* videoio(ffmpeg): fix rejecting on acceleration device name mismatch

* videoio(ffmpeg): fix compilation USE_AV_HW_CODECS=0, add more debug logging

* videoio: rework VideoAccelerationType behavior

- enum is not a bitset
- default value is backend specific
- only '_NONE' and '_ANY' may fallback on software processing
- specific H/W acceleration doesn't fallback on software processing. It fails if there is no support for specified H/W acceleration.

* videoio(test): fix for current FFmpeg wrapper

3f14341629 Change Keymap wording for gray image in curve mode
Instead of being a copy of line 76, line 79 instead correctly indicates that it will show a histogram for a gray image in curve mode, as given by the code block at line 103 referencing image "gray" instead of image "im".
