Heads-up: R packages for OpenTimelineIO, RcppOTIO and rotio

[TroyHernandez]

Hi OTIO maintainers,

I wanted to give you a heads-up before I submit an R OpenTimelineIO
package to CRAN.

• RcppOTIO: https://github.com/cornball-ai/RcppOTIO
  R bindings to the OTIO C++ library (time types, schema objects, tree
  construction, JSON round-trips, edit algorithms, schema versioning).
  Published through a drat repo so it can serve as an optional validation
  oracle.

• rotio: https://github.com/cornball-ai/rotio
  A pure-R OTIO document model: reader/writer, edit algorithms, and schema
  behavior, no compiled code. This is the package headed to CRAN.

Building these packages is what led me to the edit-algorithm bug fixed in
#2025: my parity tests kept disagreeing with libopentimelineio until it
turned out the disagreement was upstream.

rotio uses RcppOTIO in optional tests to validate JSON output and behavior
parity against the C++ implementation. The goal is a lightweight OTIO
package for R users that runs without a C++ toolchain, while still checking
behavior against the reference implementation where available. Both
packages are Apache-2.0 to match upstream.

Before I submit rotio to CRAN, I'd appreciate a quick once-over on:

• naming
• scope
• schema/version behavior
• anything that looks likely to confuse OTIO users or maintainers

Thanks for building OTIO!

Hi Troy, I'd like to suggest raising attention in the ASWF #opentimelineio Slack channel for wider visibility.
