Ian Gudger e29a02239e binary: append slices
A new optimization in Go 1.11 improves the efficiency of slice extension:
"The compiler now optimizes slice extension of the form append(s, make([]T, n)...)."
https://tip.golang.org/doc/go1.11#performance-compiler

Before:
BenchmarkMarshalUnmarshal-12    	 2000000	       664 ns/op	       0 B/op	       0 allocs/op
BenchmarkReadWrite-12           	  500000	      2395 ns/op	     304 B/op	      24 allocs/op

After:
BenchmarkMarshalUnmarshal-12    	 2000000	       628 ns/op	       0 B/op	       0 allocs/op
BenchmarkReadWrite-12           	  500000	      2411 ns/op	     304 B/op	      24 allocs/op

BenchmarkMarshalUnmarshal benchmarks the code in this package, BenchmarkReadWrite benchmarks the code in the standard library.
