allow to download price data in EUR and other fiat currencies

[giocaizzi]

Fixes issue:
Fixes issue of being able to download price data only in USD.

Changes:

• cryptocmd.utils.download_coin_data has new argument fiat, a string code to specify that price data is returned in the desired fiat currency eg. USD, EUR
• cryptocmd.core.CmcScraper has new attribute fiat. Default is USD but can now be changed during initialization.

Great changes @giocaizzi 👍 🍰. Maybe it now would be great if we can include fiat in the default filename core.py#L228

[giocaizzi]

good idea! 👍 i have added fiat in the default filename and modified the commented line just above it for clarity. core.py#L191-L194

[guptarohit]

@giocaizzi I guess we need to do similar changes on core.py#L230-L231

p.s. export_csv method is going to be deprecated.

[giocaizzi]

oops, got confused between the two methods. added the same changes to export.
