M5StickV - "Value Error Sensor control fail" when call sensor.get_gain_db().

The same problem also found in sensor.get_exposure_us() and etc about camera control functions.

I use maixpy_v0.4.0_44_g95f00f0_m5stickv.bin (firmware)
and maixpy-ide-mac-0.2.4.dmg (IDE on MAC)

The api seems not implement yet , we will implement it in next release.
