Description

For the next major release we should look into changing money_column to support a single currency. Rather than both currency and currency_column, we could have only currency and make it accept something responding to call or to_s.
Example:

class Product
  money_column :price, currency: ->(product) { product.currency }
  money_column :price_usd, currency: 'USD'
end

I think this is easier to reason about and will help clean up the code

Research direction

No files or tests are named; start by locating the current money_column implementation and its handling of currency and currency_column. Done would mean deciding and implementing one currency option that accepts either a fixed value or a callable value, with the existing behavior and release migration addressed.
