bug: commonJS headerReadResultPromisable instanceof Promise is false

[jrk94]

Issue description

commonJS headerReadResultPromisable instanceof Promise is false

Expected Behavior

Support commonjs

Actual Behavior

In commonJS with the instantiation like await (new Function('return import("node-llama-cpp")')() as Promise<typeof import("node-llama-cpp")>); when calling the const model = await llama.loadModel() it will result in the metadata being undefined and give an error with general.alignment headerReadResult.metadata["general.alignment"]; this is due to the the fact that headerReadResultPromisable instanceof Promise resolves as false instead of true, therefore the promise is not yet resolved

Steps to reproduce

Try to use this in commonjs.

@jrk94 Please fill in the Steps to reproduce and My Environment. I cannot help you otherwise.
Also, do you use a bundler to run your code? What is your tsconfig.json file like? What nodejs version?
