BME68X_LEN_FIELD * 3 too big for smbus in i2c read/writes for some systems. #33

Description

@kp101

According to SMBus standard in some linux, the I2C read/write has a limit of :

I2C_SMBUS_BLOCK_MAX is 32 bytes.

But bme68x_defs.h has

#define BME68X_LEN_FIELD is UINT8_C(17)

So, in bme68x.c where function 'read_all_field_data' defined the buff length as BME68X_LEN_FIELD x 3 which is greater than I2C_SMBUS_BLOCK_MAX resulting in chop offs in the register read/writes.

thank you for your attention in this matter.
