You can use my bootimg NASM script, which is 100% FLOSS (Fair License) and runs atop NASM (2-clause BSD license). Unfortunately it cannot initialise the BPB of the boot sector loader file. (It uses NASM's incbin directive which only allows including entire files, unlike say dd.) Also, it likewise does not support file attributes (yet), nor file datetimes. Additionally you have to list every file to include in the image, you cannot just instruct it to take a directory (because NASM does not have any interface for a source file to walk a directory).

For writing a boot sector loader there's my instsect application but it only supports operation with an actual DOS drive, not with image files (yet).
