Hey @solarsamuel,
this is not bad... i was like really confused why this doesn't work.
But now I understand. It's fairly simple you are trying to run a amd64 executable on arm32 processor.
Your raspberry pi needs different executables. This repository provides only binaries for common PC (amd64).
So what you have to do is to build it yourself.
Here check this tutorial, everything should be explained there.

But basically it should be something like:
# install your systems go package apt-get install golang-go cd PaneldueFirmware/Tools/gobmp2c go build ./gobmp2c
