This method returns a new werd constructed using the blobs in the input all_blobs list, which correspond to the blobs in this werd object. The blobs used to construct the new word are consumed and removed from the input all_blobs list. Returns nullptr if the word couldn't be constructed. Returns original blobs for which no matches were found in the output list orphan_blobs (appends).
