changes made to 14b8ec7e.

- saves the doc idx by order in dataset
- saves the full ctx. we can turn this off it is too much memory
- saves the idx of the fewshot examples
- saves the source (test/val) of the fewshot examples
- TODO: We now need to return the pred/target from process_results
- TODO: Make it so override-ed process-resutls don't have to re-impl
this.

Remove arguments from main.py.

Add "decontamination" prefix to ngrams arguments.

for some reason putting it in LM and having it be inherited breaks

model_args should only be things that affect output of the model
therefore, stuff like batch size, device, etc shouldn't be in there
