Add error messages to translationFn call

[nf-s]

We should handle errors thrown here

catalog-converter/src/converters/helpers.ts

Lines 164 to 170 in 97834f3

	if (Object.prototype.hasOwnProperty.call(source, propV7)) {
	const value =
	!is.string(prop) && typeof prop.translationFn === "function"
	? prop.translationFn(source[propV7])
	: source[propV7];
	if (typeof value !== "undefined") destination[propV8] = value;
	}

and wrap them in a nice error message - eg "Failed to translate prop someProp: errorMessage"
