[Suggestion] Do not create output file until at least one chunk was received

Basic Information

• Node.js version: v20.5.1

Describe the bug

Currently if you initiate a task, no matter how early it fails (failed to fetch m3u8, failed to parse, failed to download any chunk, etc.), it will still create a .ts file.

I personally think this is unexpected and minyami should only start creating this file once it started downloading actual chunks.

Same goes to temp folder -- but from my observation, at least if the fetching of m3u8 was failed it will not create temp folder, which is good.

[Last-Order]

Good suggestion. Should be fixed in the next version.
