Use the
petsctools.attach_options
and associated functions in the TAO solver.Also adds a "
tao
" optional dependency set to the pyproject.toml includingpetsc4py
andpetsctools
.The
attach_options
functions are not in the current release ofpetsctools
so this will have to wait until a new release is made, and means there's a minimum version restriction in the pyproject.toml.There is a lot of duplication with #214, which removes
OptionsManager
andflatten_options
from the tao_solver file, but that PR is is compatible with the currentpetsctools
release so can go in now.
