ObjFW  Check-in [2e9336b1ef]

Overview
Comment:Rename OFDeflateStream -> OFInflateStream

It makes more sense to have one class for inflating and one for
deflating instead of having one that does both, as having one that does
both requires more memory per instance when only inflating or deflating
is used.
