Add patterns from overevaluate

[IridescentVoid]

As discussed, the following overevaluate features will be incorporated into base hex casting:

• Extirpating Gambit: cutting a list into three parts, before/iota/after
• Reflecting Gambit: flip top three iotas
• Bubbling Gambit: swap 2nd and 3rd iotas from the top
• Dioscuri Gambit II: dup n iotas
• Tutu's Gambit: does nothing at all
• Janus' Gambit: terminates the hex
• Atalanta's Gambit: skip to next iteration in a thoth's loop
