* Added tcp fragmentation for freedom outbound * Added TCP_NODELAY to outbound sockopt * Changed fragment parameters to accept ranges and changed strategy to use length * Changed packetNumber to packets, supporting range. * Refactored the freedom fragment logic * Refine Write() --------- Co-authored-by: RPRX <63339210+RPRX@users.noreply.github.com>
