v3.0.0-alpha-0217

New features

• Support for BEP47 has been added, thanks to @jpmikkers .
• Support for BEP52 is progressing well. It is now possible to fully download and verify BEP52 torrents using a magnet link. Metadata, and v2 piece hashes, can be dynamically requested from peers.

General improvements

• The most frequently invoked BitField method, BitField.NAnd has been improved to fast-path several common cases.
• The BitField class has been refactored to follow the same pattern as Memory and ReadOnlyMemory. BitField class is mutable and can be transparently cast to ReadOnlyBitfield.
