Disabling JPEG carver not working

Hi,

In Bulk Extractor 2.1.1, the following command still carves out jpeg files to the jpeg directory:

bulk_extractor -o be_out -S jpeg_carve_mode=0 /path/to/source/dir

I see https://github.com/simsong/bulk_extractor/issues/468 fixed some issues related to this, including switching the flag from jpeg_carved_carve_mode to jpeg_carve_mode and adding a test for jpeg_carve_mode=2. It seems that may there's still an issue, at least when setting jpeg_carve_mode=0.
