Pull request overview

This PR extends the Python bindings to expose output-related configuration and runtime state, enabling Python-side inspection/control of outputs.

Changes:

• Switch pybind11 holders for OutputType / NetcdfOutput to std::shared_ptr to support returning/storing outputs via shared ownership.
• Expose OutputType.file_number and OutputType.next_time as Python-accessible fields.
• Expose MeshBlockOptions.outputs (and related output fields) plus add MeshBlock.get_outputs() to retrieve a block’s configured outputs.

The Python binding for OutputType.increment_file_number() was removed, but it is still used in multiple in-repo Python entrypoints/tests (e.g., tests/test_crater.py and several scripts under examples/). This will break those callers at runtime. Consider re-adding increment_file_number() as a thin convenience/deprecated alias (internally updating file_number), or update all in-repo call sites and any documented API expectations accordingly.

Suggested change

	.def_readwrite("next_time", &snap::OutputType::next_time);
	.def_readwrite("next_time", &snap::OutputType::next_time)
	.def(
	"increment_file_number",
	[](snap::OutputType &self) {
	// Deprecated convenience alias: prefer manipulating file_number directly.
	self.file_number++;
	},
	"Deprecated: use 'file_number += 1' instead.");
