The documentation for Configure Stem Long Press may be simplified. The value sent should be regarded as the final state, not enable / disable commands.

Simplified version:

04 00 04 00 09 00 1A [modes] 00 00 00

modes: Bitwise OR of all the enabled modes:

| Bit | Value | Name         |
|-----|-------|--------------|
| 0   | 0x01  | "Off" mode   |
| 1   | 0x02  | ANC          |
| 2   | 0x04  | Transparency |
| 3   | 0x08  | Adaptive     |

At lease 2 different modes must be enabled.

Example: `0x06` = `0x02` + `0x04` = ANC and Transparency mode selected (while Off and Adaptive deselected)

Also, yeah, this shouldn't be hard-coded:

Thanks! I don't know why I thought these weren't based on the final state.

Implementing this right now.
