[BUG] useIno option does not appear to use custom ino values in stat struct

[paulrobello]

After inode 1 for the root fs node I set starting inode number at 100 and increment it with every created node.
I use the ino field in the stat struct.
When doing a stat on any of my fuse nodes I can see the count starts from 1 and does not jump to 100+.
const fuse = new Fuse('./mnt', ops, {
debug: false,
displayFolder: false,
autoUnmount: true,
force: true,
kernelCache: false,
useIno: true // <- this does not appear to be used
});

Looking at _fuseOptions in index.js I can see that use_ino is not something that is pushed into the -o option returned from the function for the fuse mount options.

Added option in PR33
