docs: document the processing and chunk configuration types - #33

Proposed Changes

Part of splitting #22 into small pull requests that can be reviewed one at a time. It is stacked on #32 (fix/chunk-length-validation), so it shows only its own change; merge #32 first.

Documentation only, apart from moving the ChunkConfiguration case fields onto their own lines so that each can carry a doc comment:

• AwaitParallel and AwaitSequentialParallel send up to MaxConcurrent values to the selector at once and queue the others, instead of sending all values at once.
• ProcessingOptions: every field, Default, Parallel, MaxConcurrent and AwaitOperation. ConfigureAwait configures only R3's await of the selector result, not the awaits inside the selector, and CancelOnCompleted also discards the queued elements.
• ChunkConfiguration: every case and case field, with a pointer from ChunkWindowBoundaries to chunkByBoundaries; the helpers read the default time provider when they are called.

Types of changes

What types of changes does your code introduce to FSharp.Control.R3?
Put an x in the boxes that apply

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist

Put an x in the boxes that apply. You can also fill these out after creating the PR. If you're unsure about any of them, don't hesitate to ask. We're here to help! This is simply a reminder of what we are going to look for before merging your code.

• Build and tests pass locally – 0 warnings, Fantomas is clean, and the tests that exist at this commit pass
• I have added tests that prove my fix is effective or that my feature works (if appropriate) – in test: cover the library with integration tests #22, the top of this stack
• I have added necessary documentation (if appropriate)

Further comments

The documented behaviour is pinned by ProcessingOptionsTests.fs, MapAsyncTests.fs and ChunkTests.fs in #22.
