ansi-wl-pprint conversion package

This package defines a converter from the old ansi-wl-pprint document type to the new prettyprinter one. Its purpose is making packages that only generate ansi-wl-pprint data available to the prettyprinter ecosystem.

Note the difference to the prettyprinter-compat-ansi-wl-pprint module, which does not convert any data, and instead provides an API that mimicks ansi-wl-pprint, while secretly being prettyprinter-based behind the curtains. This package on the other hand does a proper conversion.
