This specifically applies to all Mastodon extractors and all
extractors with a 'basecategory', i.e. 'booru', 'foolslide', etc.
Values inside those general config locations wouldn't be recognized
when a value with the same was set on the 'extractor' level.
For example 'extractor.mastodon.directory' should be used over
'extractor.directory' when both are set, but this was impossible
with the previous implementation.
(fixes#843)
Instead of a dictionary/object, input file options are now specified
by a 'key=value' pair starting with '-' for options only applying to
the next URL or '-G' for Global options applying to all following URLs.
See the docstring of parse_inputfile() for details.
Example option specifiers:
- filename = "{id}.{extension}"
- extractor.pixiv.user.directory = ["Pixiv Users", "{user[id]}"]
-spaces="are_optional"
-G keywords = {"global": "option"}
- speed improvements, especially in the 'interpolate' function
- 'interpolate' now prioritizes base-level values if they exist
- "username" is chosen before "extractor.<category>.username"
- -u/--username & co can now override config-file values
