stm_reflash fetches firmware from a personal repo
https://source.puri.sm/firmware/ttxs-firmware/-/blob/purism/scripts/stm_reflash.sh#L3 by default fetches the firmware from @angus.ainslie repo:
URL=https://source.puri.sm/angus.ainslie/ttxs-firmware/-/jobs/323584/artifacts/raw/src/build/ttxs.bin
Shouldn't that rather use a latest firmware from this repo?
