Extend check-total to look beyond statements and read from Nyc config like .nycrc

Extend `check-total` to look beyond statements. It appears, at the moment, [check-total only checks against statements](https://github.com/bahmutov/check-code-coverage/blob/master/bin/check-total.js#L30) and not against `lines, functions or branches`.

```bash
check-total --from coverage/coverage-summary.json --min 80
```

### Expected
Also support
```bash
check-total --from coverage/coverage-summary.json --min 80 --functions 63 --branches 53
```
Which would check against lines, functions and branches as well.

Additionally, if `.nycrc` is present then it can read the thresholds if not provided on cli.
