• TlsStream for sync ftp.
• AsyncStdTlsStream for async-std ftp.
• TokioTlsStream for tokio ftp.

• Removed async feature; use either async-std or tokio.
• Removed async-native-tls; use either async-std-async-native-tls (for async-std) or tokio-async-native-tls (for tokio) instead.
• Renamed async-native-tls-vendored to async-std-async-native-tls-vendored.
• Removed async-default-tls.
• Removed default-tls
• Renamed async-rustls to async-std-rustls.

• Added tokio support along with async-std.
• Use tokio feature to use tokio
• Use tokio-rustls feature to use tokio with rustls
• Use tokio-async-native-tls feature to use async-native-tls with tokio

• Added custom_data_command to perform the execution of custom data commands.
• Added close_data_connection to close the DataStream once consumed after executing custom data commands.
• Made get_lines_from_stream public to easily read String lines from the DataStream.

Issue 85: Fixed retr method signature on the AsyncFtpStream to allow passing a closure taking the stream reader.

stream .retr("test.txt", |mut reader| { Box::pin(async move { let mut buf = Vec::new(); reader.read_to_end(&mut buf).await.expect("failed to read stream"); Ok((buf, reader)) }) }) .await
