Initial attempt at implementing resnet50 for use with CIFAR data.

[drewoldag]

Attempting to run this from the command line with:
fibad train --runtime-config example_config.toml

However, it's not currently running for a couple of reasons:

1. Resnet50 accepts an input, num_classes which we can define in our config, but if num_classes isn't also defined in the main FIBAD config, it throws an error. This is a FIBAD bug that must be addressed.
2. Something is wrong with the example CIFAR dataset. It doesn't seem to load as expected. This is likely also a bug on the FIBAD side that is a result of the work to move away from DataLoaders and toward Datasets.
