Complete, ready to use TypeID parse (c# 7+)

[Chern0byl]

Hi there, it has been pretty long since I've released anything for the SRO community, guess it's time. It isn't anything big, but yet will be useful for many devs. Basically, this peace of code lets you easily "parse" type ids that are widely used @ sro.

It uses value tuple language feature, which is only available in c# 7 and newer.
