Request messages sequence violation

[Avdeev87]

The following occurs quite often

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. (Parameter 'to')
	at System.Net.Http.Headers.RangeItemHeaderValue..ctor(Nullable'1 from, Nullable'1 to)
	at System.Net.Http.Headers.RangeHeaderValue..ctor(Nullable'1 from, Nullable'1 to)
	at MonoTorrent.Connections.Peer.HttpPeerConnection.ReceiveAsync(Memory'1 socketBuffer) in MonoTorrent.Client\MonoTorrent.Connections\HttpPeerConnection:cs
	...

This is a consequence of the fact that HttpPeerConnection.SendAsync(Memory<byte> socketBuffer) receives non-sequential data.

In ConnectionManager.TryProcessQueue(TorrentManager manager, peerID id), messages from the queue are dequeuing sequentially, but when several threads exist in parallel, this data can be transferred to PeerIO.SendMessageAsync() with an order violation.

SocketPeerConnection has similar issues

This problem can be fixed by prohibiting asynchronous retrieval from the message queue, but this will slightly affect performance
