3dr updating firmware error using sik_uploader.py

I have this error when flashing 3DR radio firmware on linux using APM planner 2.

> Flashing with firmware
> ./sik_uploader/firmware/1.9/radio~hm_trp.ihx

And I checked out the codes:
Here: https://github.com/diydrones/apm_planner/blob/master/sik_uploader/sik_uploader.py#L207
It does not have the property in module _fdpexpect_.

So I think there should be a fix.

Start in sik_uploader/sik_uploader.py around line 207 and inspect how fdpexpect is imported and how its timeout exception is referenced. Reproduce the Linux firmware upload failure if possible; done means the uploader handles the timeout without the reported AttributeError and proceeds with the intended error handling.
