ludfjig/hyperlight-samples

1. Make sure you have Hyperlight repo cloned to a repo adjacent to this one, and check out the following Hyperlight branch in that repo git fetch origin pull/104/head:musl_subtree && git checkout musl_subtree, (replace origin with the name of your upstream remote). This step will not be necessary once the PR merges.
2. In this hyperlight-samples repo, run :
3. just cp-from-adjacent-hl-repo to copy over header and lib files required for building the guest
4. just download-qjs to download quickjs
5. just patch-qjs to patch quickjs.
6. just build-qjs-guest to compile the guest
7. just run samples/pi_bigfloat.js to compile and run the host cli application, passing in a javascript file to be executed. There are more samples in the samples folder.

minor tweaks

You might need to increase the MEMORY_LIMIT and BUFFER_LIMIT in main.rs, in case the current memory limits are not enough to execute your javascript code without erroring out.
