Changes in v0.3.0 (first release after fork form AccelStepperI2C v0.2.2):

• implemented I2C delay auto adjust, see I2Cwrapper::autoAdjustI2Cdelay()
• new TM1638liteI2C module added
• added/tested ATtiny support
• eliminated need for hardware reset, changed firmware and all modules so that they reset to their initial state by software
• new optional delay parameter for I2Cwrapper::reset(unsigned long resetDelay = defaultResetDelay)
• introduced feature modules which do not interface to some new peripheral, but only change the firmware's behavior in some way
• new feature module _statusLED_firmware
• moved I2C address storage&retrieval config options to new feature module _addressFromFlash_firmware
• added new feature module _addressFromPins_firmware
• added new feature module _addressFixed_firmware

• removed diagnostics from firmware (it was partly AccelStepperI2C specific and needs a better second life as a module in its own right)
• fixed lots of minor errors and inconsistencies
