feat(result): add Result.unwrapRaw

[favna]

This is essentially a shortcut for:

	return result.match({
		err: (error) => {
			throw error;
		},
		ok: (value) => value.data[0]
	});

which can then be written as:

return result.map((value) => value.data[0]).unwrapRaw();

This is useful when instead of throwing a ResultError you want to instead throw the inner error (i.e. ArgumentError for Sapphire, see sapphiredev/framework#528, or a FetchError from @skyra/safe-fetch, something that brought about this change)
