* Add support for CEVA BNO08x 9DoF sensor. Also includes implementation of CEVA SH-2 and SHTP protocols.
* Replace machine.I2C with drivers.I2C interface to remove dependency on machine package
* Replace Pin functionality with that provided by tinygo.org/x/drivers/internal/pin
* Unexport fields on SensorValue and replace with accessor methods. Add check for correct SensorID validation
* Add example to smoketest.sh
* Change build target for smoketest to match development environment.. Probably not important, but matches reality.
* Fix decoding of some sensor data: Step Counter, Tap Detector, Flip Detector. These are experimental.
* Refactor to allow SPI/UART etc. SPI is currently under development, but is omitted from this commit.
Example code has been moved to i2c subdirectory.
This commit introduces some major refactoring changes. It introduces a "Buser" interface and tries to remove any I2C specific code from the core. It still retains a couple of I2C specific fields in the "Config" struct ("Address" and "ReadChunk") but they are ignored in the as yet uncommited SPI code.
* Fix CRLF -> LF for gofmt
* Update smoketest to point to new example file
