Renamed the extractor selection from the cli to '--input' since it
decides the various input formats that are used to gather annotations
from.
Renamed the template selection from the cli to '--output' since it
control the output format that annotations are displayed/written in.
This also somewhat more closely mirrors pandoc cli options, which are
generally a good guide to follow.
Switching this project over to the uv package manager as a pilot project
for my personal use.
Since this project is not yet widely used I can use it as an
experimental playground for discovering uv further without interrupting
anybody's workflow.
Added markdown with atx style headers, can be chosen as
alternative markdown template on the cli.
The existing 'markdown' template will still default to
setext-style headers.
Formatters (previously templates) were pure data containers before,
continating the 'template' for how things should be formatted using
mustache. The formatting would be done a) in the exporters and b) in the
annotations.
This spread of formatting has now been consolidated into the Formatter,
which fixes the overall spread of formatting code and now can coherently
format a whole output instead of just individual annotations.
A formatter contains references to all documents and contained
annotations and will format everything at once by default, but the
formatting function can be invoked with reference to a specific
annotated document to only format that.
This commit should put more separation into the concerns of exporter and
formatter and made formatting a concern purely of the formatters and
annotation objects.
