Vijay Janapa Reddi 712ccc0c27 feat(datasets): add tinydigits and tinytalks educational datasets
Add curated educational datasets for TinyTorch milestones:

TinyDigits (~310 KB):
- 1000 train + 200 test samples of 8x8 digit images
- Balanced: 100 samples per digit class (0-9)
- Used by Milestones 03 (MLP) and 04 (CNN)
- Created from sklearn digits, normalized to [0,1]

TinyTalks (~40 KB):
- 350 Q&A pairs across 5 difficulty levels
- Character-level conversational dataset
- Used by Milestone 05 (Transformer)
- Designed for fast training (3-5 min on laptop)

Both datasets follow Karpathy's ~1K samples philosophy:
- Small enough to ship with repo
- Large enough for meaningful learning
- Fast training with instant feedback
- Works offline, no downloads needed
