c0f61a2e15 Rework how DVAE tokens are ordered 
It might make more sense to have top tokens, then bottom tokens
with top tokens having different discretized values.

d9936df363 Add gpt_tts dataset and implement inference 
- Adds a script which preprocesses quantized mels given a DVAE
- Adds a dataset which can consume preprocessed qmels
- Reworks GPT TTS to consume the outputs of that dataset (removes logic to add padding and start/end tokens)
- Adds inference to gpt_tts

46e9f62be0 Add unet with latent guide 
This is a diffusion network that uses both a LQ image
and a reference sample HQ image that is compressed into
a latent vector to perform upsampling

The hope is that we can steer the upsampling network
with sample images.
