Update image requirement from 0.23.12 to 0.24.1

[dependabot]

Updates the requirements on image to permit the latest version.

Changelog

Sourced from image's changelog.

Version 0.24.1

Bug Fixes:

• ImageBuffer::get_pixel_checked would sometimes return the incorrect pixel.
• PNG encoding would sometimes not recognize unsupported color.

Version 0.24.0

Breaking changes

Structural changes:

• Minimum Rust version is now 1.56 and may change in minor versions until further notice. It is now tracked in the library's Cargo.toml, instead, by the standard [package.rust-version] field. Note: this applies to the library itself. You may need different version resolutions for dependencies when using a non-stable version of Rust.
• The math::utils::{nq, utils} modules have been removed. These are better served through the color_quant crate and the standard library respectively.
• All codecs are now available through image::codecs, no longer top-level.
• ExtendedColorType and DynamicImage have been made #[non_exhaustive], providing more methods instead of exhaustive matching.
• Reading images through the generic io::Reader, as well as generic convenience interfaces, now requires the underlying reader to be BufRead + Seek. This allows more efficient support more formats. Similarly, writing now requires writers to be Write + Seek.
• The Bgra* variants of buffers, which were only half-supported, have been removed. The owning buffer types ImageBuffer and DynamicImage fundamentally already make a choice in supported pixel representations. This allows for more consistent internal behavior. Callers are expected to convert formats when using those buffers, which they are required to do in any case already, and which is routinely performed by decoders.

Trait reworks:

• The Pixel trait is no longer implemented quite as liberally for structs defined in the crate. Instead, it is now restricted to a set of known channel which ensures accuracy in computations involving those channels.
• The ImageDecoderExt trait has been renamed to ImageDecoderRect, according to its actual functionality.
• The Pixel trait and its Subpixel field no longer require (or provide) a 'static lifetime bound.
• The Pixel trait no longer requires specifying an associated, constant ColorType. This was of little relevance to computation but made it much harder to implement and extend correctly. Instead, the private PixelWithColorType extension is added for interfaces that require a properly known variant.
• Reworked how SubImage interacts with the GenericImage trait. It is now a default implementation. Note that SubImage now has inherent methods that avoid double-indirection, the trait's method will no longer avoid this.
• The Primitive trait now requires implementations to provide a minimum and maximum logical bound for the purpose of converting to other primitive
