"your device (gfx906:sramecc-:xnack-) is unknown!"

Setting gfx906:sramecc-:xnack- is not possible due to the name already having a colon in it for obvious reasons. export BELLMAN_CUSTOM_GPU="gfx906:sramecc-:xnack-:3840"

- Rust panic: Invalid BELLMAN_CUSTOM_GPU!

Solution: ability to escape characters or put a check in for a integer after the colon.
