extra ^M characters in multipart-related series download

[pieper]

When downloading a series using dicomweb wado-rs to get multipart content of type application/dicom, the contents of the download from the proxy is different from accessing the Google dicomweb directly.

In this image the left side is from the proxy and the right side is from google.

This is the proxy URL:

https://proxy-dot-idc-dev.appspot.com:443/v1beta1/projects/idc-dev-etl/locations/us-central1/datasets/idc_tcia_mvp_wave0/dicomStores/idc_tcia/dicomWeb/studies/1.3.6.1.4.1.14519.5.2.1.2744.7002.150059977302243314164020079415/series/1.2.276.0.7230010.3.1.3.8323329.18234.1440001306.224430

And this is to access the corresponding series from Google.

export PROJECT_ID=chc-tcia

export URL=https://healthcare.googleapis.com/v1beta1/projects/$PROJECT_ID/locations/$REGION/datasets/$DATASET_ID/dicomStores/$DICOM_STORE_ID/dicomWeb/studies/1.3.6.1.4.1.14519.5.2.1.2744.7002.150059977302243314164020079415/series/1.2.276.0.7230010.3.1.3.8323329.18234.1440001306.224430
echo $URL

Note that this is not an issue for OHIF, but causes issues for other uses of the proxied content.
