[gpuCI] Forward-merge branch-22.04 to branch-22.06 [skip gpuci]

- Adjusts the installation section for the RTL-SDR example notebook to properly install all of the NeMo ASR toolkit dependencies as well as SoapySDR with RTL-SDR support
- Installs pyaudio + SoapySDR with LimeSDR support for the general SDR example notebook
- Adds a disclaimer to both notebooks that they will not work without an SDR device connected

This PR makes some changes to `get_pinned_mem` so that it properly handles dtypes other than `uint8` - it also adds some additional handling for `shape` so that integers are now supported, and the output array actually has the input `shape`.

This PR resolve pinned buffer IO issues introduced in de9be48; essentially, if `read_bin` is passed a `buffer` and `dtype`, it should prioritize `buffer.dtype` over `dtype` to ensure that the buffer and memmap sizes match up.

Still want to add IO tests to ensure that things are working properly, and potentially alter `read_bin` to raise an error if both `buffer` and `dtype` are provided.

This PR adds a [pre-commit](https://pre-commit.com/) configuration to this repo to enforce the Python style checks - it also modifies the gpuCI style check to use pre-commit instead of just `isort`.

The pre-commit configuration can probably be expanded to include CUDA style enforcement with `clang-format`, but this seemed like a decent starting point.

This PR convert the `from sources` build we are doing in GPU test job to a `conda build`. This is done for the following reasons:
- This is required step to improve the Ops CI/CD setup to a more convenient pipeline
- This is required to start using `conda` compilers and `mamba` to build RAPIDS packages
- This prevent us from manually managing and installing the dependencies in GPU job
- This ensure the packages can be installed
- This ensure the tests are running and working against the package content and not the build results. Currently the Python packages are not tested.

This may increase the global pipeline time, but the usage of `mamba` should resolve this as `mamba` is faster than `conda` to build packages

Use `mambabuild` to build `conda` packages. This should speed up the builds and help to debug `conda` conflict issues
