Import file from AWS bucket

I am using cadquery to convert files from STEP to STL.

For this, the files are stored on an AWS server with public-read.

To import, I use the following statement:

```
afile = cq.importers.importStep("https://company_bucket_name.region.amazonaws.com/file.step") # (mock link)
```

The file does exist in the real link, as going to it downloads the file. However, when attempting to import via cadquery, I get:

```
ValueError: STEP File could not be loaded
```
