Added test and benchmark for MapFn, which confirmed slow performance due to regexps. Before: ``` go test -bench=BenchmarkMapFn -benchmem goos: linux goarch: amd64 pkg: github.com/transparency-dev/incubator/vindex/cmd/sumdbindex cpu: Intel(R) Xeon(R) CPU @ 2.20GHz BenchmarkMapFn-24 99729 12438 ns/op 565 B/op 10 allocs/op PASS ok github.com/transparency-dev/incubator/vindex/cmd/sumdbindex 1.329s ``` After: ``` go test -bench=BenchmarkMapFn -benchmem goos: linux goarch: amd64 pkg: github.com/transparency-dev/incubator/vindex/cmd/sumdbindex cpu: Intel(R) Xeon(R) CPU @ 2.20GHz BenchmarkMapFn-24 1361030 873.2 ns/op 288 B/op 4 allocs/op PASS ok github.com/transparency-dev/incubator/vindex/cmd/sumdbindex 1.280s ```
