`feat`: Adds additional validation for incoming request's asset symbols. #202

This PR adds validation for the symbols. If the symbols contain invalid symbols, the sanitize function clears the field. The validation picks up on the empty strings and causes an error to be returned. This is added to prevent calls to the exchanges for invalid symbols.
