MRT encoder

This version adds the MRT encoding support for BGP4MP and TableDump v1 (V2 will be supported later). This means users can now writes MRT files for BGP updates received/filtered/crafted. This enables a bunch of potential applications such as per-AS MRT archiver, or BMP-to-MRT data stream.

Examples:

• Stream BGP messages, filter for AS3356's originated messages, archive to a destination MRT file: https://github.com/bgpkit/bgpkit-parser/blob/main/examples/mrt_filter_archiver.rs
• Stream from RouteViews Kafka stream, and write all messages directly to a MRT file: https://github.com/bgpkit/bgpkit-parser/blob/main/examples/real-time-routeviews-kafka-to-mrt.rs
