pip install fails with python 3.10

Hi,

pip install triangle fails with python 3.10.

Setup: fresh conda-arm64 environment with python 3.10 on Macbook Pro (M1 Pro chip). Installation works with python 3.9 and otherwise identical conditions, making me suspect that it is a general incompatibility with python 3.10.

Let me know if you need the log, but the error should be easy enough to reproduce.
