Allow users to get the trader price

[rHermes]

This allows the users to check what a trader would give for the items in their inventory.

We shouldn't panic but instead return a proper error type.

Yeah, I originally had a proper error type here, but I saw that in places like the get_trader_prices_raw if the response doesn't match up, you panic with expect. I am all for errors though, I just couldn't find an appropriate error type.

Is this different than functions like get_trader_items? I don't really understand the purpose of this function other than as a helper function. Is this not possible to implement without the private get_trader_prices_raw function?

[rHermes]

The get_trader_items returns the items the trader is willing to sell as far as I know? This returns the price the merchants is willing to pay for items in the users inventory. I am very new to this API, so I could very much be wrong.

As I see it in the get_trader_items you are limiting the returned items to the items returned by get_trader_items_raw. This is the items the trader has and is not the full range of what they can buy. That is why this needs the get_trader_prices_raw function, to return the full set of prices for items the sellers can buy from player.

Hope that made sense and thanks for an awesome library!
