Does Godot have file streams?

I need to write data to a binary format and am having trouble finding any kind of streaming file writer in Godot. Right now I'm trying to make do with PackedByteBuffer, but it's not easy to use. I also found StreamPeerBuffer, but I cant' seem to get any data out of it once I've written to it. Is there any way I can write a sequence of binary data into a buffer?

StreamPeerBuffer seems to be working for me in 4.0 rc1:

var buffer := StreamPeerBuffer.new()
buffer.put_data([170, 75, 42, 123])
buffer.seek(0)
print(buffer.get_data(4)[1]) # prints [170, 75, 42, 123]
buffer.seek(2)
print(buffer.get_8()) # prints 42
buffer.seek(4)
buffer.put_data([234, 0, 128, 77])
buffer.seek(0)
print(buffer.get_data(buffer.get_size())[1]) # prints [170, 75, 42, 123, 234, 0, 128, 77]
