Adding STMicro LIS3DH sensor support. This module is based on the one for lis2ds12 (thanks, jontrulson!), but as sensors are noticeably different, the contents underwent major rework. Examples and basic API are left the same. Tested on Intel Edison with Arduino board using both I2C and SPI. Signed-off-by: Alex Tereschenko <alext.mkrs@gmail.com>
