Chowda alters MMIF formatting, removing prettification

[owencking]

Description

When I run a CLAMS app with pretty=true, it should return MMIF files with prettified spacing instead of having all the spaces and line breaks removed.

Reproduction steps

Create a pipeline and a batch with the app called app-swt-detection_par01. This is defined with this endpoint:
http://app-swt-detection?pretty=true&sampleRate=500&minFrameCount=5

Run the batch with some asset.

Open resulting MMIF in a text editor.

Expected behavior

Downloaded MMIF files should be the same as the CLAMS app output.

Additional context

It common for the Clammer and the Brandeis team to open a MMIF file at look at the first 50 or 100 rows, especially the metadata fields. This is very difficult when the formatting is gone.
