The `papis tags` command is extended with the functionality to not
just display all tags used in current query, sorted alphabetically,
but also to display how often they appear.
Use `papis tags -c` to show a space-separated count of how often
each tag is used next to the tag name, in descending order.
Papis reload will now only rebuild the cache of the currently
active library by default. To rebuild the cache of all libraries
papis knows, simply supply the `--all` switch.
Papis show can now show output styled by python-rich if it
is in the environment. Otherwise falls back to normal
console printing.
Added more information to output (journal, volume, issue,
type, doi) but also added `-s` switch which returns to
old single-line behavior for copying to other programs.
