Flash programming errors out on a colorlight i5 development board

When I run various ecpdap flash commands, I always get an error. Sometimes the command still works, but flashing itself does not.
Results for different options:

I'm pretty sure this is the same bug that by coincidence someone else reported a few hours ago on the same board in #9; are you able to try building from this repository (or just cargo install ecpdap if you have Rust installed)? If not I can also upload a prebuilt binary to check against.
(Here's a pre-built Linux executable which hopefully will work for your flash, so long as your system has similar libc/libusb versions to me: ecpdap_linux_x86_64_spi-flash_0_2_2.zip)
The issue is fixed with the new binary. Thanks!
