Please update debian package with 1.2 (also forwarding #1054080)

[nabijaczleweli]

I see https://github.com/AllwineDesigns/stl_cmd/releases/tag/v1.2 but the debian package is still at 1.1.
And the watch file is broken and doesn't find anything, so here's a working one:

version=4
opts=\
pgpmode=self,\
filenamemangle=s%.*/@ANY_VERSION@%@PACKAGE@-$1.tar.gz.asc%,\
downloadurlmangle=s%api.github.com/repos/([^/]+/[^/]+)/git/refs/tags/@ANY_VERSION@%github.com/$1/releases/download/v$2/stl_cmd-$2.tar.gz.asc%g,\
searchmode=plain \
 https://api.github.com/repos/AllwineDesigns/stl_cmd/git/matching-refs/tags/ \
 https://api.github.com/repos/[^/]+/[^/]+/git/refs/tags/@ANY_VERSION@

gbp import-orig --uscan works and imports 1.2 with this d/watch.

Also forwarding https://bugs.debian.org/1054080:

I want to see the difference between two STL files. I ran the following
commands:

$ stl_boolean -a one.stl -b two.stl -i intersection.stl
$ stl_boolean -a one.stl -b intersection.stl -d one-additions.stl
$ stl_boolean -a two.stl -b intersection.stl -d two-additions.stl

Both of the two -d commands failed, stl_boolean segfaulted before producing any output.

I then cloned the upstream repo, which is several commits ahead of the v1.1 tag that the current debian package is based on, and those executables worked fine.

So this will be fixed by 1.2 probably (but please check!). The .stls are attached, see the webview.
