Add color space configuration feature

[ltatarev]

Added setColorSpace function needed on iOS as a way to configure the color space for image processing.

This change was needed to ensure consistency when displaying images with color matrix filters across iOS, Android, and web platforms. Android defaults to sRGB color space, and achieving parity with this behavior was the primary motivation for this implementation.

Changes:

• iOS Implementation: Added setColorSpace() static method to FasterImageViewManager that configures the global CIContext. The initial approach was to pass colorSpace as a prop, but was unsuccessful because CIContext configuration must be set globally at initialization rather than per-image. Supports sRGB, displayP3, linearSRGB, and genericRGB color spaces.

• Android Limitation: Coil 2.4.0 does not expose ImageLoader.Builder.colorSpace() (available in Coil 3.x), preventing color space configuration at the loader level. Implementation would require a custom decoder component to apply the color space during decoding, which is more complex and less reliable than using the native API. The Android implementation could be revisited if/when upgrading to Coil 3.x.

Visual examples from example app show how the update looks on iOS:

iOS, no filter, no color space	iOS, "bright" color matrix filter, no color space	iOS, "bright" color matrix filter, sRGB color space

Android, no filter	Android, "bright" color matrix filter
