maybe insteed of using compoud we could simply create translations for units and for suffix? 
For example:

```
second: "{1} %count% second|[2,Inf] %count% seconds"
minute: "{1} %count% minute|[2,Inf] %count% minutes"
# etc..
suffix:
  past: "ago"
  future: "from now" 
```

And use those translations in both difference and preciseDifference humanizers?
