Subject: [PATCH 018/232] Fix Constant types, remove reshapes, rework Gather

Operators no longer manipulate the shape of the output tensors, however, Gather no longer works with the new axis values which are pulled from the node. The tests also prove that ONNX Gather fails to operate on the input data if data is of rank 2, index is of rank 1 and axes=0. Before this change axis was set to a fixed -1.

+# GGML ONNX Runtime
+
+## Getting Started
+
+### Installation
+
+```bash
+pip install ggml-python[onnx]
+```
+
+### Usage
+
+```python
+import onnx
+from ggml.contrib.onnx import GgmlRuntimeBackend
+
+# Load an ONNX model
+model = onnx.load("model.onnx")
+
+# Create a runtime session
+ggml_backend_rep = GgmlRuntimeBackend.prepare(model)
+
+# Run inference
+input = np.random.randn(1, 3, 224, 224).astype(np.float32)
+output = ggml_backend_rep.run([input])
+```
+
+## Technical Overview
+
+The GGML ONNX runtime is a backend for the [ONNX](https://onnx.ai/) model format. It is designed to be used as a drop-in replacement for the ONNX Runtime which leverages ggml for efficient model inference on a wide range of devices.
+
+To use the runtime:
+
+- Models are first converted from PyTorch, TensorFlow, and other frameworks to ONNX
+- ONNX models are then optimized for ggml inference. This includes:
+    - Weight Quantization
+    - Dynamic Subgraph Detection
+    - GPU Offloading
+- The optimized ONNX models are then executed in the GGML ONNX runtime
+
+
+## Operator Support
+
+This table is generated from [`operator_sets.h`](https://github.com/onnx/onnx/blob/main/onnx/defs/operator_sets.h) and may not include all ONNX operators. These are core operators available in all versions starting from ai.onnx version 1.

+The GGML ONNX runtime is built on top of the [ONNX](https://onnx.ai/) and [GGML](ggml.ai)
+
+The core of the runtime was written by Andrei Betlen (@abetlen), David Miller (@dmille), and 
+Mohammadreza Anvari (@mrezanvari)
+
+This work would also not be possible without the ggml community, in particular @slaren for their work on the ggml backends and memory allocation api.

+# Debugging
+
+## Error: `SIGSEGV` or `Aborted (core dumped)`
+
+Godspeed! You are about to enter the world of debugging native code.
+If you are seeing a `SIGSEGV` or `Aborted (core dumped)` error something has gone horribly wrong.
+A good first step is to try to reproduce the error with a debug build of `ggml-python` and `ggml` and then use a debugger like `gdb` to step through the code and find the issue.
+
+
+```bash
+$ git clone https://github.com/abetlen/ggml-python.git
+$ cd ggml-python
+$ make build.debug # this preserves debug symbols
+$ gdb --args python3 your_script.py
+```
+
+From there you can use `run` to start the script and `bt` to get a backtrace of native code and `py-bt` to get a backtrace of python code.
+
+Additionally, you should use python's built in `breakpoint()` function to set breakpoints in your python code and step through the code.
