[Example] Refine folders

Fixed #176

[juntao]

Hello, I am a code review agent on flows.network. Here are my reviews of changed source code files in this PR.

---

wasmedge-ggml/whisper/Cargo.toml

Potential issues

1. The edition field is set to "2021", which is not a valid Rust edition; the correct editions are "2015" and "2018".
2. The dependency version for wasmedge-wasi-nn should ideally be more specific or use a range to avoid breaking changes from newer versions, e.g., "^0.8.0".
3. There is no explicit license field in the Cargo.toml, which could lead to confusion regarding the legal usage of the package.

Summary of changes

• Summary of Key Changes:

• Refactored Folder Structure: The primary directories were reorganized to improve clarity and maintainability.

• Updated Imports: File paths in import statements were adjusted to reflect the new folder structure.

• Configuration Adjustments: Configuration files were modified to accommodate the changes in directory names.

Potential issues

1. Issue 1: Incorrect tensor shape and data type - ctx.set_input(0, TensorType::F32, &[1, wav_buf.len()], &wav_buf)?; assumes the WAV buffer contains raw f32 values directly, which is typically not the case. The buffer likely contains PCM samples that need to be converted to f32 and properly shaped according to the model's input requirements.

2. Issue 2: Potential panic in String::from_utf8(output_buffer).unwrap() - If the output buffer does not contain valid UTF-8 encoded text, this will cause a runtime panic. This should be handled gracefully by using .expect("Invalid UTF-8 in output") or another method to manage potential errors.

3. Issue 3: Hardcoded output buffer size 2048 - The size of the output buffer is hardcoded, which may not accommodate all possible outputs from the model. This could lead to truncated results or incorrect behavior if the actual output exceeds this size. Consider dynamically allocating the buffer based on model requirements or querying the expected output size beforehand.
