rusty_money

• ISO: Fixed symbols for BHD, ISK, NPR, UYU and alpha code for UYW.

rusty_money now supports defining your own currencies and has a cryptocurrency module. It no longer depends on lazy_static!,
is a bit faster and and simpler to use. Many breaking changes were needed to support this, so upgrade with care!

• define_currency_set! allows you to create your own custom currency modules. @jimpo
• CryptoCurrencies (Bitcoin, Ethereum) are now available in the crypto module.
• Removed dependency on lazy_static! and made library thread safe.

Breaking Changes:

• Money::new was deprecated, please use Money::from_minor instead.
• Money::from_str() accepts a currency reference iso::USD instead of string "USD".
• Money requires lifetime and currency type annotiations.
• money! macro was deprecated, please use Money::from_str instead.
• Currency::get() was deprecated, please reference currencies directly by their module like iso::USD.
• The old Currency module is now called iso::Currency.
• Currency::from_string is now iso::find and accepts &str instead of String @ObsceneGiraffe.
• ExchangeRate::add_or_update_rate was deprecated, please use ExchangeRate::set_rate instead. @jimpo.

• Upgraded dependencies.

• Bugfix: Incorrect metadata for CZK, HUF, ZMK [@zacharra]
• Feature: Money objects can be multiplied by Decimals [@sjoerdsimons]
