Description

```
Node n;
n.set({ 42, 3.1415});
```
Yields:

```
n.set({ 42, 3.1415});

We would want to promote the int to a float in this case (as we do for yaml and json parsing)

Not sure what level of C++ wizardry we will need to figure out how to make that happen.

Research direction

Start in src/libs/conduit/conduit_node.hpp around the initializer-list set overloads cited in the compiler output, and reproduce Node n; n.set({42, 3.1415}). Determine how mixed numeric types are handled by the existing overloads. Done means the integer is promoted to float for this call, consistently with the stated YAML and JSON parsing behavior.
