i2c_sda, i2c_scl, spi_mosi, spi_miso, spi_sclk without HW_PIN_*, bh1750

platformio: 
- add bh1750 to _max
- define rotary defaults for wemos

usermod_bh1750
- Remove HW_PIN_* and replace by i2c_sda etc
- add appendConfigData

usermods mpu6050_imu, rtc, 4ld, pinmanager
- Remove HW_PIN_* 

change SDA2:pin (etc) to SDA:pin
