Hid-flash 64-bit binaries

[fpistm]

Hi @Serasidis

Hope you are fine 🙂

Did you test 64-bit binaries ?
I would like to switch on 64-bit version as the arm-none-eabi toolchain only support 64-bit since 1 year.
I've built hid-flash for Windows ans Linux.
On windows it works while on Linux a segmentation fault is raised.
I will try to debug to understand why.
It would be fine to also provides this version

Digging into the code, I've found the issue.
It is linked to #30.
Since I've change my Laptop, the udev rule was not present causing the fail on Linux and so the seg fault.
Applying the patch fix the issue (thanks @matthijskooijman)

I've just add a specific warning for Linux about the udev rule:

   }
