Add compatibility with TFEconData

[servadestroya]

nosoop/SM-TFEconData queries the game for items. Much less of a hassle for end users, but it carries a hefty amount of offsets and signatures that has to be kept in sync. In fact, in the readme there's an example for getting taunt data.

nosoop/SM-TFEconDataCompat seems to implement all of the natives used by either the tf2idb or tf2ii version of this plugin. It should be a drop in replacement
