Block API insert and insertMany don't support BlockTunes

[WolfBearGames]

When inserting blocks with the insert() or insertMany() methods applied Block Tunes are ignored. I looked at the code and only the "data" property for a block is used to create it. the "tunes" property is not handled.
So it is impossible to insert BlockData that had Block tunes applied without losing them.

I had created a BlockTune to have different display variants for paragraphs... now I might have to rework this and fork the paragraph tool to insert the variants i need directly into the plugin.
