v0.3.1: Fix uploading to Google Artifact Registry

Fixes an incompatibility with blob uploading, when the registry gives a relative URL in the Location header.

Full Changelog: v0.3.0...v0.3.1

v0.3.0: Delete v1 support & more

v1 manifests are no longer supported, v2 manifests will always be used. If this breaks you then you can complain to me but also just keep using an older version. Also other breaking changes in the API from moving things around.

I plan on moving things around more, but this was probably one of the bigger ones.

v0.2.0: Uploads & some OCI support

Revived the manifest and blob upload functions.

Implemented some basic support for handling OCI manifests.

Tested with Deno 1.18.

v0.1.2: Deno 1.9 support

Auth broke in Deno 1.9 due to denoland/deno#10367

This release includes a workaround to continue working on 1.9.

v0.1.1: Blob downloading, and refactoring

Add Azure repo test
