Client
The Client can now fetch from local (with ClientConfig.MonitoringPrefix prefix file:// or gzip+file://) or archived logs (with ClientConfig.MonitoringPrefix prefix archive+file://).
The new ClientConfig.AllowRFC6962ArchivalLeafs, LogEntry.RFC6962ArchivalLeaf, and ReadTileLeafMaybeArchival fields and function support parsing RFC 6962 logs archived as static CT logs.
The new (*Client).Entry method fetches a single log entry by index.
The new (*Client).TileReader method returns a torchwood.TileReader interface, which has ReadTiles and ReadEndpoint methods.
(*Client).Fetcher is now deprecated and returns a torchwood.TileReader interface like (*Client).TileReader. This interface has the same methods as Fetcher, so most code should work unchanged.
