table improvement: add CPU/GPU state comparison column

[juliasloan25]

ClimaLand has direct comparisons between the state of CPU and GPU runs, which is helpful to ensure minimal discrepancies between the two (see example build). It could be helpful for us to display something similar, although we do expect to see some differences between runs on CPU and GPU. This is a lower priority task, but could be implemented if we decide it would be helpful in the future.
