feat: update geostyler & prepare for next release

BREAKING CHANGE: Uses the next major version of GeoStyler and the
related parser packages etc. If you want to include your custom
parser here, you'll probably have to depend on the next major
versions of all geostyler packages involved (ideally using an esm
build).
