`noise_resids` in `WidebandTOAResiduals`

Author: scottransom

CHANGELOG-unreleased.md

@@ -20,6 +20,7 @@ the released changes.
 - PLSWNoise: a Fourier basis stochastic solar wind model. See Hazboun et al. 2022 for details.
 - Explicitly specify the Tspan for power-law GP noise parameters (TN*TSPAN)
 - Parallel execution and work stealing in CI tests
+- Make `WidebandTOAResiduals.noise_resids` available as a `@property`
 ### Fixed
 - `TimingModel.total_dm()` now returns zero when no DM component is present in the model.
 - Made `TimingModel.toa_covariance_matrix()` not explicitly dependent on `ScaleToaError`
