www/wget2: add port: File and recursive website downloader
GNU Wget2 is the successor of GNU Wget, a file and recursive website downloader. Designed and written from scratch it wraps around libwget, that provides the basic functions needed by a web client. Wget2 works multi-threaded and uses many features to allow fast operation. In many cases Wget2 downloads much faster than Wget1.x due to HTTP2, HTTP compression, parallel connections and use of If-Modified-Since HTTP header. WWW: https://gitlab.com/gnuwget/wget2
Unlike wget, this was placed into www category as it does no longer
support ftp.
