Bad pixels in original data from provider cause weird pixel values after spatial homogenization.
This applies only to scenes/bands that have to be resampled during spatial homogenization.
Here is an example with test job 'Test_Sentinel2A_SingleGranuleFormat_CompletePipeline' (Sentinel-2A__MSI__L1C_T32TLT_A007970_20161231T103428_image_data_L2A):
Proposed solution:
Implement bad pixel removal into L1A that interpolates bad pixels.
