Secondary action layer shift to layer #8 is buggy.

[parke]

Describe the bug

Chrysalis 0.13.2 (and previous versions?) say:

Due to firmware limitations, shifting to layers above "# 8" is not supported via secondary actions.

However, this is incorrect. In reality, the maximum addressable layer is 7, not 8. (Presumably, 3 bits specify the layer, allowing for layers 0-7.)

To Reproduce

Steps to reproduce the behavior:

1. Set the primary action of any key to the letter 'U'.
2. Click on "Secondary action"
3. Select "Layer shift"
4. Select layer "# 8"

The key will now display "Leader # 7". (If a letter other than 'U' is used, the key will probably display something else.)

Expected behavior

Layer 8 should not be selectable as a secondary action.
