Allow use of multiple converters on assembler
When you want to use multiple converter with assembler (exemple PDF and specific HTML), there is 2 way :
- Use 2 different extension based on assemble, but if the clean tag is set, the assembler path is cleaned and document generated with the first extension call is removed so there is an error during the site-generation.
- Another way may be to call the assemble with multiple converter instead on only one. This way allow to only do the assembly ones and call all the converter as wanted.
