zach fd95729d8d fix(kernel): length function should return 0 for invalid offsets (#635 )

Fixes #634

valid offsets instead of assuming the provided offset is valid

Extism kernel

The Extism kernel implements core parts of the Extism runtime in Rust compiled to WebAssembly. This code is a conceptual re-write of memory.rs with the goal of making core parts of the Extism implementation more portable across WebAssembly runtimes.

See lib.rs for more details about the implementation itself.

Building

Because this crate is built using the wasm32-unknown-unknown target, it is a separate build process from the extism-runtime crate.

To build extism-runtime.wasm, strip it and copy it to the proper location in the extism-runtime tree you can run:

$ sh build.sh
