Title: Getting rate for the last working day

Hello,
When You have a document where a date isn't working date, You should still be able to get avg. rate for it. So I changed the code to do this.

It's an option:
```NbpExchange::Config::get_rate_from_last_working_date = true```

The next step is to calculate holidays (using https://github.com/alexdunae/holidays gem)

Pozdrowienia :)
