Incorrect Analysis: resistor-color-duo

[SleeplessByte]

Describe the incorrectness
The helper colorCode is optimal, yet the comment is:

The helper method `colorCode` is not optimal. The helper can probably be the same as the
solution to `resistor-color`. Mentor the student to retrieve their solution and/or optimise 
their helper.

⚡ Warning: We cannot guarantee the analyzer worked correctly on this point. Please 
double-check if it made a mistake, and if it did please open an issue here so the analyzer

Additional context

The actual issue is as follows:

• the helper is only marked as optimal if it's exported, but that's incorrect. In this exercise, it should NOT be exported.
• the helper is also determined as "first constant that is not value, which is probably not what we want.
