nwis.py warned at module top-level, and dataretrieval/__init__ star-imports nwis, so `import dataretrieval` emitted a DeprecationWarning for every consumer (including waterdata-only users) and failed to import entirely under `-W error::DeprecationWarning`, which is common in CI. Deprecation is already signaled where it matters: the @_deprecated decorator emits a per-function warning on every nwis call. Removed the redundant module-level warning; the per-function warnings are unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Remove the module-level warning. Deprecation is already signaled where it's actionable: the
@_deprecateddecorator wraps every public nwis function and emits a per-functionDeprecationWarningon use (with a thread-local guard so layered wrappers warn once). That targeted mechanism is unchanged.Verification
