Fix manifest script SHA HASH when files have different line endings (#2278)

Sometimes when someone is editing a file on their system, the line endings get mixed or change to a different system. PoB expects them to use CRLF so if you hash a file based on different line endings then it can result in the wrong hash and PoB will not download it
We now use a regex to normalise all the lines before hashing so that we always get a CRLF hash
