PMFP-optimized k-Oracle, plus supporting Utils

[TheVinhLuong102]

This PR covers the following:

• A h1st.contrib.pmfp module that contains an Predictive Maintenance / Fault Prediction ("PMFP")-oriented implementation of the k-Oracle architecture

• Supporting h1st.utils for Data Processing (in particular, a ParquetDataset structure for managing and processing Parquet files on local FS & S3), and miscellaneous other helpers

• A basic h1st CLI that currently includes commands for PMFP (e.g. h1st pmfp oraclize, h1st pmfp predict-faults)

This is really old. Should be closed one way or another. @TheVinhLuong102 what should be done here?

Outdated.
