Use the correct region for stratum servers on Z-Pool
In the settings of nemosminer, I have set a location - EU, but in the miner window I see that the default location is used.

Here is an example setup from Z-Pool

```
STRATUM SERVERS - North America <na> - Europe <eu> - South East Asia <sea>
ccminer example:
-o stratum+tcp://<algo>.<region>.mine.zpool.ca:<PORT> -u <WALLET_ADDRESS> [-p c=<SYMBOL>,<OPTIONS>]
```

I did something wrong, or is it a miner problem?
