Describe the problem you'd like to have solved

The license today points to https://raw.githubusercontent.com/auth0/jwtdecode.android/master/LICENSE I would like to suggest to change url to the well known https://spdx.org/licenses/MIT.html url.

This make tools like cashapp's licensee gradle plugin to recognice what license that is being used.

Describe the ideal solution

Change URL to license file

Alternatives and current workarounds

Manually configure the current url as allowed license

licensee {
    allowUrl("https://raw.githubusercontent.com/auth0/jwtdecode.android/master/LICENSE") // MIT License
}
