(defn derivation-path
"The derivation-path multi-arity function. The first version takes
four arguments: a `coin-type`, an `account` index, a `chain` type,
and an `address` index. It uses these values to construct a string
representing a path to a specific wallet address. Throws an
exception with an error message if the `coin-type` in not found in
`coin_types.edn`. A second version taking two arguments is used to
derive an account address from a `coin-type` and an `account`
index."
