Exports and downloads

[Arun Prasad]

Work in progress:

https://ambuda.org/texts/downloads/ contains two downloads: metadata.json (list of all texts with source info, URLs for download, authors, etc.) and tei-headers.xml (list of all <teiHeader> elems from all documents on the site).

The goal is programmatic access to the full library for easier ingestion by other projects.

Still missing:

- bulk downloads of texts themselves. Certainly XML, likely TXT, not sure on other formats (eg probably not PDFs in each choice of script)

- `updated_at` to see if a text changed

- license information (CC0 1.0 Universal vs. various combinations of BY/NC/SA)

Added bulk downloads and `updated_at`.

Still TODO:

- bulk download is missing some texts, need to debug why.

- license information

[Arun Prasad]

- All texts available through bulk export.

- Most texts have license information.

- Plain text downloads now have better structure.

Still much more to do here, but this is enough for people to download the library for themselves.
