Suggestion: populate INFO name in warning "INFO tag id=146"

At the moment, some errors look like:

```
... Invalid BCF, the INFO tag id=146 is too large at ....
```

Would it be possible to look up the tagID and replace it with a more human readable string of the name? That would help people debug issues more easily.

An example where a better warning may have helped someone else #1532

Thanks!
