Add support for Python>=3.10

[shchur]

Currently toto-2 requires Python>=3.12

toto/toto2/pyproject.toml

Line 10 in 44ea4e8

requires-python = ">=3.12"

Is there a specific reason for this constraint? Would it be possible to decrease the lower bound to ">=3.10"?

Python 3.10 and 3.11 have not entered EOL yet (https://devguide.python.org/versions/), so it would be great if users could run Toto-2 on the older versions too.

I agree. It would also make integration with other ML libraries such as Darts easier if toto could support 3.10+.
