This release enables to optionallly create smaller eStargz images using the following flags for ctr-rmeote i convert or ctr-remote i optimize (#956).

• --estargz-external-toc: Separates TOC JSON into another image (called "TOC image"). The result eStargz doesn't contain TOC so we can expect a smaller size than normal eStargz (refer to /docs/estargz.md for the related eStargz spec).
• --estargz-min-chunk-size: Specifies the minimal number of bytes of data must be written in one gzip stream. If it's > 0, multiple files and chunks can be written into one gzip stream. Smaller number of gzip header and smaller size of the result blob can be expected (refer to /docs/estargz.md for the related eStargz spec).

Please refer to /docs/smaller-estargz.md for more details about the usage.

This release publishes a container image usable as a Kind node to ghcr.io/containerd/stargz-snapshotter:0.12.1-kind

$ kind create cluster --name stargz-demo --image ghcr.io/containerd/stargz-snapshotter:0.12.1-kind

Kind >= v0.16.0 is recommended as the image is based on kindest/node:v1.25.2 supported by kind v0.16.0 (see also: https://github.com/kubernetes-sigs/kind/releases/tag/v0.16.0 )

Please refer to README about examples with Kind cluster with eStargz.
