I tested against 7.1.0, 7.1.1, and 7.1.2, and encountered test failures for both 7.1.0 and 7.1.1.
7.1.2 seemed to encounter no failures and built successfully using nixpkgs.

Hopefully this is enough to update this requirement, though I am unsure if there is anything outside of the tests that is broken due to Pillow 7.1.0.
The Pillow<7.1 requirement/restriction was encountered in testing https://github.com/NixOS/nixpkgs/pull/77714 (see this comment)
Pillow was restricted to <7.1 in https://github.com/MIC-DKFZ/batchgenerators/commit/67f7503dbe054226cd15aa0d933b9e5c8d9c5b9a.
