Function pluginIndexArchive_read

pluginIndexArchive_read(bytes: Buffer, source: string): PluginIndex
Reads an index from archive bytes.

A single top folder (GitHub's FNNDSC-chris-plugins-<sha>/) is the root; the pax global header's comment is the commit.
Parameters
- bytes: Buffer
  The archive, gzipped or plain.
- source: string
  The source word, for the index's source and label.
Returns PluginIndex
The index.
Throws
When the archive is unreadable, an entry's path is unsafe, or the schema it carries is not JSON.
Example
```
const index: PluginIndex = pluginIndexArchive_read(readFileSync('index.tar.gz'), 'FNNDSC/chris-plugins@main');
```
