Add Tidy3D Matplotlib Styles on Import

CHANGELOG.md

@@ -14,6 +14,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Added `eps_lim` keyword argument to `Simulation.plot_eps()` for manual control over the permittivity color limits.
 - Added `thickness` parameter to `LossyMetalMedium` for computing surface impedance of a thin conductor.
 - `priority` field in `Structure` and `MeshOverrideStructure` for setting the behavior in structure overlapping region. When its value is `None`, the priority is automatically determined based on the material property and simulation's `structure_priority_mode`.
+- Automatically apply `matplotlib` styles when importing `tidy3d` which can be reverted via the `td.restore_matplotlib_rcparams()` function.
 
 ### Fixed
 - Fixed bug in broadband adjoint source creation when forward simulation had a pulse amplitude greater than 1 or a nonzero pulse phase.
