Shkarko presenterm 0.12.0

Breaking changes
- Using incremental lists now adds an extra pause before and after a list. Use the defaults.incremental_lists configuration parameter to go back to the previous behavior (#487) (#498).
New features
- PDF exports are now generated by invoking weasyprint rather than by using the now deprecated presenterm-export. This gets rid of the need for tmux and opens up the door for other export formats (#509) (#517).
- PDF export dimensions can now also be specified in the config file rather than always having them inferred by the terminal size (#511).
- Allow specifying path for temporary files generated during presentation export (#518).
- Respect font sizes in generated PDF (#510).
- Add skip_slide comment command to avoid including a slide in the final presentation (#505).
- Add alignment comment command to specify text alignment for the remainder of a slide (#493) (#522).
- Add --current-theme CLI parameter to display the theme being used (#489).
- Add gruvbox dark theme (#483) - thanks @ret2src.
Fixes
- Fix broken ANSI escape code parsing which would cause command output to sometimes be incorrectly parsed and therefore led to its colors/attributes not being respected (#500).
- Center lists correctly (#512) (#520).
- Respect end slide shorthand in speaker notes mode (#494).
- Use more visible colors in snippet execution output in terminal-light/dark themes (#485).
- Show error if sixel mode is selected but disabled (#525).
CI
- Add nightly build job (#496).
Docs
- Fix typo in README.md (#490) - thanks @eltociear.
- Correctly include layout pic (#495) - thanks @Tuxified.
Misc
- Cleanup text attributes (#519).
