Show conciseness of generated code in README/docs?

[ali-ramadhan]

Seems like other packages like to show off how short the generated LLVM or assembly code is to show that the code generated is performant. Is it worth adding something similar for DispatchedTuples.jl?

I'm not too familiar with @generated so I played around to see if the generated code was indeed concise. Looks like it is!

DispatchedSet

julia> ds = DispatchedSet((Center() => "c", Face() => :f))
DispatchedSet{Tuple{Tuple{Center, String}, Tuple{Face, Symbol}}, DispatchedTuples.NoDefaults}(((Center(), "c"), (Face(), :f)), DispatchedTuples.NoDefaults())

julia> @code_native dispatch(ds, Face())
        .text
; ┌ @ DispatchedTuples.jl:147 within `dispatch'

DispatchedTuple

DispatchedTuple{Tuple{Tuple{Center, String}, Tuple{Face, String}, Tuple{Center, Symbol}, Tuple{Face, Symbol}}, DispatchedTuples.NoDefaults}(((Center(), "c"), (Face(), "f"), (Center(), :c), (Face(), :f)), DispatchedTuples.NoDefaults())
