☃️ 0.7.0

Breaking Changes:

• The Config::set_max_udp_payload_size() method was renamed to Config::set_max_recv_udp_payload_size().
• Updated public APIs to use the ConnectionId type: accept(), connect(), negotiate_version(), retry(), Header.
• The FFI API has been disabled by default. It can be enabled during build by enabling the ffi feature (cargo build --features ffi ...).

Highlights:

• Optimized STREAM frame generation to reduce number of allocations and copies.
• Added Config::set_max_send_udp_payload_size() method to configure maximumg UDP datagram outgoing size.
• Added Connection helper methods: is_readable(), is_draining(), peer_streams_left_bidi(), peer_streams_left_uni().

• Introduced ConnectionId type to represent QUIC connection IDs.
• Implemented ABC Slow Start as per RFC3465.
