Text Model Support in Armory Library

[deprit]

We want to extend Armory Library to support the evaluation of text models, particularly LLMs. Supporting text evaluations will require the classes below.

• Text data set and data loader
• Text model wrapper
• Text evaluation metrics

LLM model sources:

• Hugging Face open LLM leaderboard
• Meta Llama repo
• LitGPT
• Vicuna LLM
• Falcon

Text evaluations and metrics:

• EleutherAI LLM evaluation harness
• TorchMetrics
