Buffer.alloc is not a function (Node.js func inside Browser context issue)

### Problem:

It seems that the library doesn't really work with Vite? I'm trying to a setup encryption decryption class in one of my apps, and I'm getting weird errors in the browser after initialising the code.

Locally I'm getting
```
build_cryptographic_materials_cache_key_helpers.ts:15 Uncaught TypeError: Buffer.alloc is not a function
at build_cryptographic_materials_cache_key_helpers.ts:15:28
(anonymous) @ build_cryptographic_materials_cache_key_helpers.ts:15
```

I've also tried creating a Codesandbox to quickly reproduce the issue: https://codesandbox.io/p/sandbox/flamboyant-kowalevski-cmgymq

But it seems we're getting a different error.

Both errors are linked to using Node packages inside the Browser context (which doesn't work). I think some of the dependencies of this package import those and thus it fails.

### Solution:

I'm not sure

Someone else had this issue but posted the issue in the wrong place: https://crypto.stackexchange.com/questions/106579/issue-with-aws-encryption-sdk-for-javascript-in-browser-buffer-is-not-defined

Bắt đầu bằng cách tái hiện lỗi trình duyệt từ build_cryptographic_materials_cache_key_helpers.ts ở dòng 15, sử dụng CodeSandbox được liên kết và thiết lập Vite đã báo cáo. Truy tìm dependency nào cung cấp Buffer và xác định ranh giới bundling cho trình duyệt; hoàn tất khi bản build cho trình duyệt khởi tạo mà không có lỗi Buffer.alloc hoặc khi có một cấu hình được hỗ trợ và được tài liệu hóa.
