Is your feature request related to a problem? Please describe.
The BSD-3-Clause license type complicates the filesystem library usage.

Describe the solution you'd like
The MIT license is more permissive, so it would be nice to apply it instead.

Describe alternatives you've considered
Any other permissive licenses are welcome.

Additional context
Our team is going to open source some library (under MIT license) and having a dependency on the BSD license is not okay then. So if the license type is not changed, we'll have to find another filesystem implementation.
