Patch issue 32

This release also adds the ability to provide your own custom B2C policy by setting the b2c_policy parameter in MSALClientConfig.
This is an optional change and should not affect your current code implementation.

Added IDTokenClaims to complete the list from the MS documentation:
https://learn.microsoft.com/en-us/entra/identity-platform/id-token-claims-reference

These now include the "roles" claim asked by steffenschumacher - Close 11

Added fixes and enhancements to the authorization checks.
- Return 401 instead of 500 in case of expired token
- Better validation process to support more clear validation errors as enum instead of general error
- Added ability to specifically request callback page after logout (not only per referrer header)
- Refactor of methods signature to target few lint warnings

Thank you rmwesley and u-iandono for your support and comments.
