hipscat.inspection takes lsdb.Catalog

[nevencaplar]

Plotting functionality in hipscat.inspection expects the input to be a hipscat.Catalog, and it fails with non-trivial error messages when trying to pass lsdb.Catalog. At the moment, a user needs to know to invoke .hc_structure on their lsdb.Catalog and pass that to the plotting function.

Make it possible for a user to pass lsdb.Catalog to hipscat.inspection in order to plot the results.

Alternatively, we could create a method on lsdb.Catalog like plot_pixels which calls the inspection method, passing in the hc_structure. This may be more intuitive for users, and avoids circular dependencies.
