[bug] wrong content-type returned via tiny-http (Rust)

### Describe the bug

Hi, I tried to use tauri to package some static files (webvm), and I found one resource `/debian_mini_20240103_7393161196.ext2` request returned `Content-Type: text/html` and `Transfer-Encoding: chunked`.

The mime type of unknown file maybe represent as binary file (`Content-Type: application/octet-stream`).

### Reproduction

_No response_

### Expected behavior

I expected the server returned `Content-Type: application/octet-stream` and `Content-Range: bytes 0-1/629145600` for `/debian_mini_20240103_7393161196.ext2`.

### Stack trace

_No response_

### Additional context

How can I configure/overwrite the mime type of a specified resource? And is there any way to make the response return `Content-Length` and `Content-Range` instead of `Transfer-Encoding: chunked`.
