Add Unimixins 0.1.16+ dep (#125)

It bundles mixinextras 0.3.5 which contains an API that the item tick
optimization requires.

Previous versions of unimixins would exhibit a similar bug as to archaicfix
0.7.2 and et futurum requiem.

Deciding to do this rather than add the dependency for mixinextras directly as
this seemed a bit more foolproof.

Fixes #124
