IAW7SMWriter V0.07

[beard]

Due to problems with the recovery mode I did now a complete rewrite of this part.

I 'bricked' my ECU several times (switch of ignition during a write)
And it was always possible to reprogramm it via the new recovery function.

If you are a user of the 7SMWriter: upgrade immediately!

Caution:

Always connect a battery charger if you use the 7SMWriter.
The Delay value in the driver has to be set to 1ms.
