c2pa-provider capability provider

Build with 'make'. Test with 'make test'.

Using the included Github Actions

If you store your source code on Github, we've gone ahead and included two actions: build.yml and release.yml under .github/workflows. The build action will automatically build, lint, and check formatting for your actor. The release action will automatically release a new version of your actor whenever code is pushed to main, or when you push a tag with the form vX.Y.Z.

These actions require 3 secrets

1. WASH_ISSUER_KEY, which can be generated with wash keys gen issuer, then look for the 58 character Seed value
2. WASH_SUBJECT_KEY, which can be generated with wash keys gen module, then look for the 58 character Seed value
3. WASMCLOUD_PAT, which can be created by following the Github PAT instructions and ensuring the write:packages permission is enabled
