zprint-filter-1.2.2

Two (relatively small) issues fixed here:

• Complex :style declarations with a vector of styles didn't work well when some of those styles also had :style keys with vector values. Issue #217.
• Added "defn-" to :style :rod since it already processed "defn".

The first issue, with :style, is important to upcoming enhancements to the VSCode zprint extension, vscode-clj-zprint.
