Add flag for xml report

[Bizordec]

I've used xmlreport.py from coverage.py as a base to add an XML support in slipcover (Cobertura-style format).

This resolves #6

Please check failure (ubuntu-latest, pypy-3.9).

I think this issue was present before this PR...

The test-build-from-source job is failing because there is no such directory starting with pp39 in manylinux container

slipcover/.github/workflows/tests.yml

Line 79 in c8f923d

python_tag: ['cp311', 'pp39']

Maybe change to cp39?

Huh, it worked for me last week... https://github.com/plasma-umass/slipcover/actions/runs/11534857119/job/32109329650

But yes, it's a different container digest, and it looks like they moved to PyPy 3.10, deleting 3.9.

Well, the point is to test building with PyPy. Let's see if SlipCover works with PyPy 3.10...

Looks like they dropped support for it 2 days ago

Yup. We have tests failing with pypy 3.10... I'll look into that tomorrow.

Oh well, PyPy 3.10 implements its own line table format, different from cpython 3.9, cpython 3.10
and cpython 3.11. I implemented it, hopefully that will work now.

Could you please create a new release in PyPI? 👀
