Release [`v0.32.0`](https://github.com/go-hep/hep/tree/v0.32.0) is out of the oven.

This release contains no major API breakage, but all around improvements and bug fixes.

This release drops support for Go-1.17 (and earlier) and is the first release with the introduction of a few generics-based APIs.

Thanks to Olivier Mengué ([@dolmen](https://github.com/dolmen)) there were a couple of house cleaning changes that have been applied (as part of the [CERN+Google Hackathon](https://gohack.devpost.com/)).
Thanks again Olivier.

There has been some work on `RNTuple` front, but nothing that can be released yet.

## brio

General clean-ups by Olivier M.

## fwk

General clean-ups by Olivier M.

## groot

- `riofs`: add generic `Get[T]` to retrieve ROOT objects
- `riofs`: export in-memory read-only `RMemFile` ROOT file

## hbook

General clean-ups by Olivier M.

## lhef

General clean-ups by Oliver M.
Olivier also reduced the amount of memory allocations in `lhef.NewDecoder`.

## sliceop

- introduce `sliceop` and generics-based functions that mimick what `sliceop/f64s` did
- implement `sliceop/f64s` in terms of `sliceop`
