0.112.0

This is the second in a series of "Giddy-up" 🏇🏽 releases, improving the performance of the following commands:

• stats: by refactoring the code to detect empty cells more efficiently, and by removing
  unnecessary bounds checks in the main compute loop. (~10% performance improvement)
• sample: by refactoring the code to use an index more effectively when available - not only making it faster, but also eliminating the need to load the entire dataset into memory. Also added a --faster option to use a faster random number generator. (~15% performance improvement)
• frequency, schema, search & validate by amortizing/reducing allocations in hot loops
• excel: by refactoring the main hot loop to convert Excel cells more efficiently

The prebuilt binaries are also built with CPU optimizations enabled for x86_64 and Apple Silicon (arm64) architectures.

0.112.0 is also a "Carousel" (i.e. increased usability) 🎠 release featuring new Jupyter notebooks in the contrib/notebooks directory to help users get started with qsv.
