Is there any interest in adding support for aarch64 (ARM64) to this package?

I am doing SMT32 development in a VM on ARM based OSX. xpack gcc and openocd are build for this architecture but the STM32Tools package is not.

There is just the 4 binaries dfu-prefix, dfu-suffix, dfu-util and hid-flash in this package that are architecture dependent and in most cases there are not used unless you are doing DFU or HID based programming.

If there is some interest I will work up a pull request.
