Build seemingly hangs when building image 0.25 crate

[tronical]

The latest version of the image-rs crate (0.25) takes literally hours to compile with the current esp-rs nightly toolchain.

Steps to reproduce:

git clone https://github.com/image-rs/image.git
cd image
cargo +esp build --release

It works with Rust nightly (and stable), i.e. it terminates within a fraction of the time.
