Change the gold price API from gram to troy ounce (or introduce an argument to specify the quantity)
The bitcoin price of the API call https://api.vaultoro.com/latest/ is provided for a gram, which is much too imprecise. Currently the price has only 4 non-zero digits. The reason is that one bitcoin is worth much more than one gram of gold. So the quantity of gold needs to be increased so that a price with more valid digits is provided. Change it to troy ounce or maybe even kilogram.
