isUserBootloader() fails to check conditions correctly

[diablodale]

depthai-core v2.27.0 isUserBootloader() fails to check conditions correctly.

I think the code needs to check what is flashed...not what is currently running since it could be running from an esoteric/embedded blob. Should also check that it is a NETWORK sensor not usb, so calling isUserBootloaderSupported() fits well.

depthai-core/src/device/DeviceBootloader.cpp

Lines 729 to 733 in 729e478

	bool DeviceBootloader::isUserBootloader() {
	// Check if bootloader version is adequate
	if(getVersion().getSemver() < Version(Request::IsUserBootloader::VERSION)) {
	return false;
	}

I think that block should instead be

bool DeviceBootloader::isUserBootloader() const {
    // Check if bootloader version is adequate
    if(!isUserBootloaderSupported()) {
        return false;
    }
