build had 18 merge-conflict marker lines committed in 6abd7ea, so bash
failed on every hook. Rewritten clean with cd + std::die guards (modbuild
has no errexit in hooks) and an indexamajig existence check after install.
desy.de/~twhite tarball URL hangs (curl: (28) timed out, 0 bytes) from Ra
and outside. Switched urls to the same release tag on gitlab.desy.de and
updated the sha256 for crystfel-0.13.0.tar.gz.
