[Fiat] Add PLN

[MicroPanda123]

• I confirm there are no other open issues about this asset
• I understand that adding the asset is at discretion of the Haveno Core Team and applying doesn't necessarily imply acceptance

What's the ISO code of the currency?

PLN

Why should it be added to Haveno? How would it benefit the project and the community?

Poland has nice cryptocurrency scene and while we don't have huge population (~38 Million people), I still think there would be a lot of people interested in trading here.

Where is the currency used?

Poland

Why would Haveno be beneficial for the people using this specific fiat currency?

Again, Poland has nice cryptocurrency scene, filled with shitty alt-coins and NFT projects, so it would be nice to have a better way to introduce people to Monero in here. Also recently current government has been acting quite "strange" recently, so it feels like more anonymous trading would be helpful.

Additional notes

It's small suggestion, I don't feel that strongly about adding it at the launch, but I hope it will be at least added at some point in the future.
