remove message STORM32_GIMBAL_MANAGER_INFORMATION from blacklist

[pv42]

The STORM32_GIMBAL_MANAGER_INFORMATION message had been blacklisted from generation due to inconsistent enum sizing not being supported (see mavlink/mavlink#1969). This is no longer an issue.

The generated code for GIMBAL_DEVICE_INFORMATION_DATA in both storm32.rs and common.rs:

impl MessageData for GIMBAL_DEVICE_INFORMATION_DATA {
    [..]
    fn deser(..) {
        [..]
        let tmp = buf.get_u16_le()?;
        __struct.cap_flags = GimbalDeviceCapFlags::from_bits(
            tmp as <GimbalDeviceCapFlags as Flags>::Bits,
        )
        [..]
    }
    fn ser(..) {
        [..]
        __tmp.put_u16_le(self.cap_flags.bits() as u16);
        [..]
    }
}

and for STORM32_GIMBAL_MANAGER_INFORMATION_DATA in storm32.rs

impl MessageData for STORM32_GIMBAL_MANAGER_INFORMATION_DATA {
    [..]
    fn deser(..) {
        [..]
        let tmp = buf.get_u32_le()?;
        __struct.device_cap_flags = GimbalDeviceCapFlags::from_bits(
            tmp as <GimbalDeviceCapFlags as Flags>::Bits,
        )
        [..]
    }
    fn ser(..) {
        [..]
        __tmp.put_u32_le(self.device_cap_flags.bits() as u32);
        [..]
    }
}
