Matching binaries

Hi! I wonder if it would make sense/ be desirable to add support for matching binaries to the Redbug syntax. In addition to the following (already supported) syntax:

```
redbug:start("x:y(<<\"hello\">>)").
```

One could also write:

```
redbug:start("x:y(<<\"he\",_/binary>>)").
```

Or even something like:

```
redbug:start("wow:do(<<_:8,_:8,0,_/binary>>").
```
