Peter Hawkins 0dbd467cea Add a C++ implementation of safe map.
Before (argument names reversed, oops, fixed in code):

```
name                                 time/op
safe_map/num_args:0/arg_lengths:1    1.43µs ± 1%
safe_map/num_args:1/arg_lengths:1    1.61µs ± 1%
safe_map/num_args:2/arg_lengths:1    1.72µs ± 0%
safe_map/num_args:5/arg_lengths:1    2.14µs ± 1%
safe_map/num_args:10/arg_lengths:1   2.87µs ± 1%
safe_map/num_args:100/arg_lengths:1  15.6µs ± 1%
safe_map/num_args:0/arg_lengths:2    1.65µs ± 0%
safe_map/num_args:1/arg_lengths:2    1.83µs ± 1%
safe_map/num_args:2/arg_lengths:2    1.97µs ± 1%
safe_map/num_args:5/arg_lengths:2    2.41µs ± 1%
safe_map/num_args:10/arg_lengths:2   3.22µs ± 2%
safe_map/num_args:100/arg_lengths:2  17.0µs ± 2%
safe_map/num_args:0/arg_lengths:3    1.83µs ± 1%
safe_map/num_args:1/arg_lengths:3    2.02µs ± 1%
safe_map/num_args:2/arg_lengths:3    2.16µs ± 1%
safe_map/num_args:5/arg_lengths:3    2.63µs ± 1%
safe_map/num_args:10/arg_lengths:3   3.48µs ± 1%
safe_map/num_args:100/arg_lengths:3  18.1µs ± 1%
```

After:
```
name                                 time/op
safe_map/num_args:0/arg_lengths:1     409ns ± 1%

safe_map/num_args:2/arg_lengths:1     777ns ± 4%
safe_map/num_args:5/arg_lengths:1    1.21µs ± 3%
safe_map/num_args:10/arg_lengths:1   1.93µs ± 2%
safe_map/num_args:100/arg_lengths:1  14.7µs ± 0%
safe_map/num_args:0/arg_lengths:2     451ns ± 1%
safe_map/num_args:1/arg_lengths:2     652ns ± 0%
safe_map/num_args:2/arg_lengths:2     850ns ± 4%
safe_map/num_args:5/arg_lengths:2    1.32µs ± 3%
safe_map/num_args:10/arg_lengths:2   2.11µs ± 2%
safe_map/num_args:100/arg_lengths:2  16.0µs ± 1%
safe_map/num_args:0/arg_lengths:3     496ns ± 1%
safe_map/num_args:1/arg_lengths:3     718ns ± 5%
safe_map/num_args:2/arg_lengths:3     919ns ± 4%
safe_map/num_args:5/arg_lengths:3    1.43µs ± 2%
safe_map/num_args:10/arg_lengths:3   2.30µs ± 2%
safe_map/num_args:100/arg_lengths:3  17.3µs ± 1%
```
