Hardcoded wasm-opt path invalid when installing jco as a dev dep

[morigs]

I've installed jco as a dev time dependency instead of global bin (npm i -D @bytecodealliance/jco).

The opt command looks for wasm-opt at ../../node_modules/binaryen/bin/wasm-opt.

However, npm installed it at the root of three to avoid duplicates (node_modules/binaryen, not node_modules/@bytecodealliance/jco/node_modules/binaryen).

Perhaps, using require.resolve('binaryen/bin/wasm-opt') will resolve the issue.

Full error text:

(jco opt) Error: node:internal/modules/cjs/loader:1152
  throw err;
  ^

Agreed we should use a node_modules backtracking technique here in whatever form.
