The `Hsla` -> `Rgba` conversion sometimes results in negative (but very close to 0) color components due to floating point imprecision, causing the `.powf(constants.main_trc)` computations in the `srgb_to_y` function to evaluate to `NaN`. This propagates to `apca_contrast` which then makes `ensure_minimum_contrast` unconditionally return `black` for certain background colors. This PR addresses this by clamping the rgba components in `impl From<Hsla> for Rgba` to 0-1.
