v0.1.0

First tagged release.

• Go: go get github.com/gofsd/shmring@v0.1.0
• Android/Gradle: shmring-v0.1.0.aar attached below, resolved via a
  Gradle ivy-pattern repository (see README Install section) -- no Maven
  registry account needed.
• Web/npm: published as shmring on npm.

Verified end-to-end on desktop (two real processes), in a real headless
browser (SharedArrayBuffer across main thread/Worker), and on a real
Android device (ASharedMemory backend, both raw and via the gomobile AAR).
