#### Testing the changes
- I tested the changes in this PR: **YES** (works with sagemath-9.5.beta8)

The new version incorporates all patches from sagemath, now we don't need any patch. Moreover, a small testsuite has been added, so we no longer need our custom quick test. The whole template is now so much simple, the library has a proper soname, etc.

Note that this new version is required for sagemath >= 9.5.beta8
