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.
