Update lut

[ternaus]

Fixes: #1997

Summary by Sourcery

Refactor image processing functions to use sz_lut instead of cv2.LUT for improved performance and consistency. Simplify the shift_hsv function by removing separate handling for different data types. Update the add_snow_texture function to use cv2.add for blending. Adjust the albucore dependency version in setup.py. Remove a redundant test case and update another for better precision.

Enhancements:

• Refactor the shift_hsv function to simplify the logic and remove separate handling for uint8 and non-uint8 images.
• Replace cv2.LUT with sz_lut for various image processing functions to improve performance and maintain consistency.
• Modify the add_snow_texture function to use cv2.add instead of cv2.addWeighted for blending snow with the original image.
• Update the adjust_brightness_torchvision and adjust_contrast_torchvision functions to use inplace=False for multiply and multiply_add operations.

Build:

• Update albucore dependency version from 0.0.17 to 0.0.18 in setup.py.

Tests:

• Remove the test_hue_saturation_value_float_uint8_equal test case from test_transforms.py.
• Update the test_random_tone_curve test in test_functional.py to use np.testing.assert_allclose for better precision in comparisons.

Hey @ternaus - I've reviewed your changes - here's some feedback:

Overall Comments:

• The change in the solarize function now modifies the input image directly instead of creating a copy. While this may be an optimization, it changes the function's behavior in a way that could surprise users. Consider documenting this change clearly or reverting to the previous behavior of not modifying the input.

Here's what I looked at during the review

• 🟢 General issues: all looks good
