TV series that list episodes through many `collection_subcollection_*`
zones (one per season):
- RC-023217__acquitted.json
- RC-022923__cry-wolf.json
Other collection that list items in one `collection_videos_*` zone:

Significant rewrite after model modification: introducing `*Sources`
objects that encapsulate metadata and fetch information (urls,
protocols). The API (#20) is organized as pipe elements with sources
being what flows through the pipe.
1. fetch program sources
2. fetch rendition sources
3. fetch variant sources
4. fetch targets
5. process (download+mux) targets
Some user selection filter or modifiers could then be applied at any
step of the pipe. Our __main__.py is an implementation of that scheme.
Implied modifications include:
- Later failure on unsupported protocols, used to be in `api`, now in
`hls`. This offers the possibility to filter and/or support them
later.
- Give up honoring the http ranges for mp4 download, stream-download
them by fixed chunk instead.
- Cleaning up of the `hls` module moving the main download function to
__init__ and specific (mp4/vtt) download functions to a new
`download` module.
On the side modifications include:
- The progress handler showing downloading rates.
- The naming utilities providing rendition and variant code insertion.
- Download parts to working directories and skip unnecessary
re-downloads on failure.
This was a big change for a single commit... too big of a change maybe.
In order to catch errors related to assumed JSON schema, regroup all
JSON data access under a context manager that catch related errors:
- KeyError
- IndexError
- ValueError
Changes the way the program information is figured out. From URL parsing
to page content parsing.
A massive JSON object is shipped within the HTML of the page, that's
were we get what we need from.
Side effects:
- drop `slug` from the program's info
- drop `slug` naming option
- no `Program` / `ProgramMeta` distinction
Includes some JSON samples.
