Renderers based on text-builder-linear

[sjakobi]

…should be faster than the existing renderers.

See https://hackage.haskell.org/package/text-builder-linear.

@sjakobi I would like to implement this. Should I create a new package, such as prettyprinter-linear, or should I directly add this to prettyprinter. Are we trying to keep dependencies low? text-builder-linear depends on bytestring, quote-quot, and template-haskell.

Thanks for the offer, @oberblastmeister! :)

Indeed prettyprinter can't easily accept dependencies on non-boot libraries. So my suggestion would be to put the new renderers in a new package prettyprinter-text-builder-linear.
