NIOFileSystem crashes when loading more than 2GB

[weissi]

Expected behavior

When requesting impossible things (e.g. loading more than 2GB into a ByteBuffer), NIOFileSystem should raise an error and not crash.

Actual behavior

Crash

Steps to reproduce

request.body = try await Data(buffer: ByteBuffer(
    contentsOf: "/tmp/4GBFile",
    maximumSizeAllowed: .gibibytes(4)
))
