Add list of software using oxipng (#646)

This adds a short list of software using Oxipng to the read me. It's not
intended to be an exhaustive list, just some ones that I'm aware of that
may have broad general interest.

I've also removed the long section about Trunk which I'm not sure is
appropriate to include in this read me. Trunk users can find
documentation on this from Trunk directly.

Lastly, I've removed the older benchmark which I'm sure has no relevance
any more.

-## Git integration via [Trunk]
-
-[Trunk] is an extendable superlinter which can be used to run `oxipng` to automatically optimize `png`s when committing them into a git repo, or to gate any `png`s being added to a git repo on whether they are optimized. The [trunk] Oxipng integration is [here](https://github.com/trunk-io/plugins/tree/main/linters/oxipng).
-
-To enable Oxipng via [trunk]:
-
-```bash
-# to get the latest version:
-trunk check enable oxipng
-
-# to get a specific version:
-trunk check enable [email protected]
-```
-
-or modify `.trunk/trunk.yaml` in your repo to contain:
-
-```
-lint:
-  enabled:
-    - [email protected]
-```
-
-Then just run:
-
-```bash
-# to optimize a png:
-trunk fmt <file>
-
-# to check if a png is already optimized:
-trunk check <file>
-```
-
-You can setup [trunk] to [manage your git hooks](https://docs.trunk.io/docs/actions-git-hooks) and automatically optimize any `png`s you commit to git, _when_ you `git commit`. To enable this, run:
-
-```bash
-trunk actions enable trunk-fmt-pre-commit
