Timeout error at 10sec when importing task with large image

When importing a task with project.import_task('path_to_image'), there is a timeout of 10 seconds and large images (20Mb) cant upload. When using WebUI it works ok.

After modifying the timeout in the import_tasks function fom (10,600) to (100,600) it worked ok...

```
# try import from file
if not os.path.isfile(tasks):
raise LabelStudioException(f'Not found import tasks file {tasks}')
with open(tasks, mode='rb') as f:
response = self.make_request(
method='POST',
url=f'/api/projects/{self.id}/import',
files={'file': f},
params=params,
timeout=(100, 600), ## ORIGINAL: timeout=(10, 600),
)
```

I am confused because I would expect to have a 600s timeout for the upload but the limit is given by the first number (10 in the original code).
