String names flip ordering when toggling orientation via button

[KCarlile]

Background

Toggling the orientation button results in the string names reversing under some circumstances. Toggle back and forth to see this bug appear. This happens on the examples page and the testing page.

Acceptance Criteria

• [x] Togging the orientation doesn't alter the string name ordering

Approach

• TBD

Notes

This is related to #36

The array.reverse() function returns a reversed array, but it also mutates the original array. This was causing the this.#config.stringNames to be reversed unexpectedly. Using the deep copy method to clone the array solved the issue: let stringNames = [...this.#config.stringNames]; // deep copy array
