Downloading the Sysinternals DU.zip

By default the Sysinternals DU.zip is downloaded from https://download.sysinternals.com/files/DU.zip.

If you need to change this, e.g. to download from an internal package repository, set the FAST_FOLDER_SIZE_DU_ZIP_LOCATION environment variable. For example:

export FAST_FOLDER_SIZE_DU_ZIP_LOCATION=https://your.internal.repository/DU.zip
