This change gets the radpajama.mk config working. This package depends
on THIRD_PARTY_GGML but it's configured to call ggjt_v1(), so that the
library will provide the old quantizers. The ggml_quantize_chunk() API
will now dispatch to older quantizers based on the configured version.

gglm Support for RedPajama Model

Ackonwledgement

We highly appreciate the great effort from the fork of gptneox.cpp. Our support of the RedPajama Model is mainly based on this implementation. We extend the model configure and fixed a bug when setting use_parallel_residual flag to False in their original implementation. We also extend the chat model for RedPajama.

Usage:

RedPajama Chat model:

Make the code:
```
  make redpajama-chat quantize-gptneox
```

Prepare the RedPajama model (f16 and q4_0) for gglm:

  bash ./examples/redpajama/scripts/install-RedPajama-INCITE-Chat-3B-v1.sh

Run RedPajama chat model (fp16):

  ./redpajama-chat -m ./examples/redpajama/models/pythia/ggml-RedPajama-INCITE-Chat-3B-v1-f16.bin \
  -c 2048 \
  -b 128 \
  -n 1 \
  -t 8 \
  --instruct \
  --color \
  --top_k 30 \
  --top_p 0.95 \
  --temp 0.8 \
  --repeat_last_n 3 \
  --repeat_penalty 1.1 \
  --seed 0

Note that you may need to install torch and transformers to run the above scripts, e.g.:

  pip install torch==2.0.0
  pip install transformers==4.28.1

Run RedPajama chat model (q4_0):

  ./redpajama-chat -m ./examples/redpajama/models/pythia/ggml-RedPajama-INCITE-Chat-3B-v1-q4_0.bin \
  -c 2048 \
  -b 128 \
  -n 1 \
  -t 8 \
  --instruct \
  --color \
  --top_k 30 \
  --top_p 0.95 \
  --temp 0.8 \
  --repeat_last_n 3 \
  --repeat_penalty 1.1 \
  --seed 0

Run other quantized version of RedPajama Chat model (Make sure you get the f16 model prepared before you run this):

Make the code to quantize the model if you have not:
```
make quantize-gptneox
```
Generate the quantized model, the supported types include: q4_0, q4_1, q4_2, q5_0, q5_1, and q8_0. For example, to run q4_1, you need to do the following convertion:
```
python ./examples/redpajama/scripts/quantize-gptneox.py ./examples/redpajama/models/pythia/ggml-RedPajama-INCITE-Chat-3B-v1-f16.bin --quantize-output-type q4_1
```

Then you can chat with the quantized model:

./redpajama-chat -m ./examples/redpajama/models/pythia/ggml-RedPajama-INCITE-Chat-3B-v1-q4_1.bin \
-c 2048 \
-b 128 \
-n 1 \
-t 8 \
--instruct \
--color \
--top_k 30 \
--top_p 0.95 \
--temp 0.8 \
--repeat_last_n 3 \
--repeat_penalty 1.1 \
--seed 0

RedPajama Base/Instruct model:

Make the code:
```
  make redpajama quantize-gptneox
```

Prepare the RedPajama Base/Instruct model (f16 and q4_0) for gglm:

  bash ./examples/redpajama/scripts/install-RedPajama-INCITE-Base-3B-v1.sh

  # Or 

  bash ./examples/redpajama/scripts/install-RedPajama-INCITE-Instruct-3B-v1.sh

Run other quantize version of RedPajama Base/Instruct model (Make sure you get the f16 model prepared before you run this). Then you can generate the quantized model, the supported types include: q4_0, q4_1, q4_2, q5_0, q5_1, and q8_0. For example, to run q4_1, you need to do the following convertion, e.g for RedPajama-Base q8_0:
```
  python ./examples/redpajama/scripts/quantize-gptneox.py ./examples/redpajama/models/pythia/ggml-RedPajama-INCITE-Base-3B-v1-f16.bin --quantize-output-type q8_0
```

Run RedPajama Base/Instruct model (e.g., RedPajama-Instruct q8_0) :

  ./redpajama -m ./examples/redpajama/models/pythia/ggml-RedPajama-INCITE-Instruct-3B-v1-q8_0.bin \
  -c 2048 \
  -b 128 \
  -n 1 \
  -t 8 \
  --color \
  --top_k 30 \
  --top_p 0.95 \
  --temp 0.8 \
  --repeat_last_n 3 \
  --repeat_penalty 1.1 \
  --seed 0 \
  --n_predict 256 \
  --verbose-prompt \
