Bug#1049835: Update to newer upstream (>= 0.3.7) to allow python3-pathos to build

[Julian Gilbey]

Package: python3-dill
Version: 0.3.6-1
Severity: normal

python3-pathos build-depends (and runtime-depends) on python3-dill (>=
0.3.7).  Please could you upgrade this package to a newer upstream
version to allow this package to build and migrate to testing.

Thanks!

   Julian
