please help me to get your lib working on my machine

Hi there!

I've successfully tried the sample from your README.md, but so far I've failed to get the sample loading images from files to work.

I've managed to setup a new rust project with the code from your examples/subimage-finder.rs and make it compile, but with both the default backend ("RuntimeDetectedSimd") and the "scalar" one it never finishes running or produces any output (passed ferris.png and ferris_eyes.png from your README.md in as parameters)

I've tried to also setup the opencv backend, but with that feature enabled, the rust compiler fails:

thread 'main' panicked at 'a `libclang` shared library is not loaded on this thread', /home/user/.cargo/registry/src/github.com-1ecc6299db9ec823/clang-sys-1.4.0/src/lib.rs:1731:1

Ah, I'm not 100% sure how I solved it, but now it works with opencv:

cargo run -- -backend opencv media/ferris.png media/ferris_eyes.png
   Compiling rust-ocr-playground v0.1.0 (/home/user/Development/rust-ocr-playground)
    Finished dev [unoptimized + debuginfo] target(s) in 4.17s
     Running `target/debug/rust-ocr-playground -backend opencv media/ferris.png media/ferris_eyes.png`
results: [(476, 377, 0.0)]
results_as_grayscale: [(476, 377, 0.0)]

But the other backends just completely lock one CPU core on 100% and never output anything:

cargo run -- media/ferris.png media/ferris_eyes.png
    Finished dev [unoptimized + debuginfo] target(s) in 0.04s
     Running `target/debug/rust-ocr-playground media/ferris.png media/ferris_eyes.png`
