    .SYNOPSIS
        Creates an HTTP header using BASIC authentication for use with Invoke-WebRequest or Invoke-RestMethod.

    .DESCRIPTION
        PowerShell 5 and below does not support BASIC authentication with Invoke-WebRequest and Invoke-RestMethod.
        This function will create a header in the format necessary to send BASIC authorization strings for HTTP

        properly formatted JSON.

#
#    1. Split the file up into 1MiB chunks.
#    2. Initiate a multipart upload.
#    3. Upload each part individually.
#    4. Calculate the file's tree hash and finish the upload.
