/** @brief Reads a multi-page image from a buffer in memory.
The function imdecodemulti reads a multi-page image from the specified buffer in the memory. If the buffer is too short or
contains invalid data, the function returns false.
See cv::imreadmulti for the list of supported formats and flags description.
@note In the case of color images, the decoded images will have the channels stored in **B G R** order.
@param buf Input array or vector of bytes.
@param flags The same flags as in cv::imread, see cv::ImreadModes.
@param mats A vector of Mat objects holding each page, if more than one.
