/**
* Download a file from URL to destination using the curl command.
*
* This function is primarily intended for downloading archives that will be extracted
* to a directory.
*
* # Arguments
*
*
* * `url` - The URL to download from
* * `dest` - The destination path where the file will be saved
* * `dest` - The destination directory where the file will be saved or extracted
* * `min_size_kb` - Minimum required file size in KB (0 for no minimum)
*
*
* # Returns
*
*
* * `Ok(String)` - The path where the file was saved or extracted
* * `Err(DownloadError)` - An error if the download failed
*
*
* # Examples
*
*
* ```
* // Download a file with no minimum size requirement
* let path = download("https://example.com/file.txt", "/tmp/file.txt", 0)?;
*
* let path = download("https://example.com/file.txt", "/tmp/", 0)?;
*
* // Download a file with minimum size requirement of 100KB
* let path = download("https://example.com/file.zip", "/tmp/file.zip", 100)?;
* let path = download("https://example.com/file.zip", "/tmp/", 100)?;
* ```
*
*
* # Notes
*
*
* If the URL ends with .tar.gz, .tgz, .tar, or .zip, the file will be automatically
* extracted to the destination directory.
