RFC: managing lists of typers (parallel typing, typing animations)

[aleontiev]

@cngu great library! I recently started learning Vue and this was one of the first components I checked out. One use-case I have been experimenting with is using multiple typers in an array (e.g. one typer per line of text). This allows for a few interesting effects (can create a quick demo if unclear):

• typing out several lines of text in parallel (e.g. simulating a synced collaborative typing session)
• typing out several lines of text in serial (e.g. simulating a paragraph typing session, with specific preset horizontal lines instead of one long line that may split arbitrarily) [EDIT: I realized this one can be accomplished already by using newlines within the text string. but typing in parallel is the main use-case]
• text-as-pixel art (e.g. running an ASCII animation in 2D with a monospace font)

I am planning to implement some or all of these and am wondering if this type of feature would make sense as a PR to vue-typer, or if this should be done in a separate library. I am happy to do it either way and am all for open-source.
