Add possibility to mirror data on individual devices

[clementleger]

Currently, transform TFLR does almost the job but reverses devices and whole device chain. On some devices, it is needed to simply reverse individual devices. Add a transform define to select this transformation only for individual devices.

Acutaly, I'm not sure this is the good way to go. My device is actually displaying things mirrored all the time. Transformation seems more likely to be used for occasional Transformation whereas my device needs it all the time.

The transform function already has a form _bool transform (uint8_t startDev, uint8_t endDev, transformTypet ttype) which allows you to specify a range of devices. for one device the start and end should be the same. Alternatively a more low level approach can use the method _bool transform (uint8_t buf, transformTypet ttype) for a specific buffer.

You have not explained the difference between a "mirrored image" and one that is "flipped L to R". To me they are the same.

As you do not describe your application it is not possible to be specific, however:

• If you always need to reverse a chain then it is possible that you have not configured the correct hardware. Please refer to the library documentation for how the setup should be.
• If you need to always reverse (flipLR) individual modules then this will need to be done in your own application as needed.

Indeed, my hardware was a FC16 ... Sorry for the disturbance :/
