adding emojis broke wasm build

[extrawurst]

with f3adda1 and adding twemoji-rs unconditionally as a dependency wordcloud-rs does not longer run in wasm environments anymore. unfortunately it will only break at runtime with:

panicked at 'called `Result::unwrap()` on an `Err` value: Error { kind: Unsupported, message: "operation not supported on this platform" }', /home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/twemoji-rs-0.1.2/src/lib.rs:10:37

could you make emoji support conditional so it could be disabled via features?

I'm quite busy with work and other projects so idk when i'll fix this but thanks for pointing it out !

I know it's been a while but just so you know I'm currently reworking the accelerating structure for collision checks, and after that I plan to tackle this issue :)

Ok, I finished reworking the acceleration structure, which is now in its own crate https://crates.io/crates/binary_raster and I added the default feature "fs" which you can disable to skip all filesystem usage (meaning it won't load emoji images and such).

It should work ? but please tell me if something is wrong :)
