This updates `fmt` to the latest version and moves to just being a copy of their repo to make updating easier (no editing their cmake / figuring out which files to minimally include). The motivation for this is now that we switched to C++ 20, there were a ton of deprecated function usages that is going away in future compiler versions. This gets rid of all those warnings.
