This pull request updates the license to include enterprise features.
The license now specifies that certain folders or files within the
distribution may be subject to different license terms and conditions,
which will be specified in a separate LICENSE file or within the file
itself. Additionally, a new Quivr Enterprise license has been added,
which restricts the use of the software to production environments only
if the user has a valid Quivr Enterprise license for the correct number
of user seats. The license also clarifies that modifications and patches
to the software can only be used with a valid Quivr Enterprise license.
Finally, the license includes a disclaimer of warranties and limitations
of liability.
