need firmware support for OMNIBUSF4V3

[sujal141005]

Current Behavior
I'm using an AliExpress F4 flight controller with the ICM-42688 gyro. The flight controlle when flashed wth the OMNIBUSF4V3 does not show any gyro movement in inav. After modifying the code to switch from the BMI270 and MPU-6500 to the ICM-42688, I still encountered build errors when compiling for the omnibusf4v3 target, I'm really a beginner.

Desired Behavior
I would like support for the ICM-42688 gyro sensor to be added for the omnibusf4v3 target.

Suggested Solution
Add proper support for the ICM-42688 gyro in the firmware for this flight controller.

Who does this impact? Who is this for?
This is for users with flight controllers using the ICM-42688 gyro and also whoever is trying to use this or similar fc for planes.

Additional context
I'm using an AliExpress F4 flight controller with the ICM-42688 gyro. Link to the flight controller: [https://www.aliexpress.com/item/1005007354050504.html?spm=a2g0o.cart.0.0.6e8938daC6wFCO&mp=1#nav-specification].

I am hesitant to start making changes to the Airbot Omnibus target, which works perfectly well for Omnibus boards, in order to have it instead run a completely different board from a different manufacturer.

If the manufacturer of this board would like to provide the needed information, we might be able to make a target for that board. Messing around with the target for a well-known, well-supported board from a reputable manufacturer in order to have it run a no-name Ali board that we don't have data for ... I'm not sure that makes sense.

I understand where you're coming from but I really just want help creating a custom target since you have the build environment ready just like it says in the docs. And that once a target header is made future people can just find this issue and fix their problem without a new board needing to be added to inav source code. I would be very grateful if you could help me out with this. everything other than the gyro seems to be working fine.

You can unzip the attached file and test it. It's not in any way an official INAV target.
It hasn't been tested - by me or anyone else. You can volunteer to test it if you wish.
It may fly very well for you. It may fly upside-down. It may fly away.

you're a life saver! everything seems to be working so far, thank you so much! i will have to test it on ground, will update if anything goes wrong.
