udpspeeder: Add new package udpspeeder to implement Forward Error Correction (FEC) for UDP VPNs like OpenVPN

Maintainer: @codemarauder
Compile tested: Yes
Run tested: x86_64 PCEngines APU

Description:

A Tunnel which Improves your Network Quality on a High-latency Lossy Link by using Forward Error Correction,for All Traffics(TCP/UDP/ICMP)
It does it by sending redundant packets and re-arranging them to account for packet loss over the link. It uses Reed–Solomon code.
