Remove file size check from Requests downloader

We cannot actually do this check. The Content-Length value will be the size after being further encoded or compressed. While we can find out what it was compressed with via the Content-Encoding header, we cannot match the downloaded length with the Content-Length header as requests will automatically decompress/decode according to the Content-Encoding header.
