Need Review about my scanner library

Hello everyone,

I wrote a little library that makes scanning stuff for media files :

For the possibilities of this lib :

It behaviour is almost customizable to your liking but It doesn’t seem to reach its people.

What can you suggest for that ? (I already rewrote the readme and examples n times ^^)

Other : I think I will add transducers (more info here) instead of Lodash methods to increase performance. Do you have some examples of benchmark with this stuff ? It is quite uncommon …

Thanks for your help
