Problem with directory name when pass options object.

[umartinez22]

When options object is passing by arguments like var engine = torrentStream(link, options);, the options object is mutated and the path value will be the same for others execution.

For example:

var engine = torrentStream(link, options);
engine = torrentStream(otherLink, options);

Then when the torrent is downloading the directory name (with hash) is the same for all file.

Posible soluction:

• Copy the object options into the function torrentStream insted of mutate the object.
