Previously, #450 added support for automatic library grouping. However, some users reported that
they were getting a 401 when using custom authentication such as LDAP. Therefore, that PR was
reverted (#524). This PR adds back the support for automatic library grouping for jellyfin
authentication users using the endpoint `/Library/MediaFolders` and fallsback to User views endpoint
if they're unable to sync the libraries (some, not all LDAP users had issues. Some reported that it
worked despite having custom authentication). Once it falls back to user views endpoint for syncing,
now it will detect if automatic grouping is enabled giving a warning that its not supported when
using some custom authentication methods. This PR also fixed collection syncing by expanding the
boxsets when syncing.
