Components of material property output should not be optional parameters

2

### Bug Description A reasonable user would expect the entire vector to be output with a MaterialStdVectorRealAux into an auxvariable. Having the component default to 0 does not show them...

## Reason See discussion User who does not want to use git thought he could skip committing. But no because we use git in our build system, probably to check...

Use temperature bounds in multigroup mode temperature

refs #2402 @meltawila # Checklist - [x] I have performed a self-review of my own code - [x] I have run [clang-format](https://docs.openmc.org/en/latest/devguide/styleguide.html#automatic-formatting) (version 15) on any C++ source files (if...

Facilitate use of TFPs with (v,e) variable set

The log grid in e should help with those simulations having e reach from 1e5 to 1e12 and the grid output will help debug the conversions Some parameters were being...

### Bug Description Peter was trying to model a loop and stitch each component He could not get the transfinite generator to stitch until the sidesets were flipped back to...

### Motivation We are exploring the dependence of the WCNSFV and INSFV flow solutions on the Rhie Chow coefficients. This issue will be used to reference this effort. It will...

Uniformize parsed capabilities

## Reason ParsedAux can only couple in variables and xyzt ParsedMaterial can do materials, variables, functions, pps ParsedFunction can do PP, scalar variables, functions, xyz So we could do more...

### Bug Description h is computed as _cv * T + p / rho it's missing the reference energy offset e_0 cp is set to 0, but taking the derivative...

This could be more robust than bicubic. It definitely is more approximate, see the increased diffs in unit testing

### Motivation We are hitting errors with negative temperatures and cant understand why. one reason could be the wide range in 'e' so we need a log spaced grid the...
