TSV8 pager

Sort of like git diff and git log, we should have it for pp proc, etc.

Glad to find this by looking for pretty printing of CSV / TSV / TSV8, looking forward to the new pp features.

Right now we don't have enough people to do this, but I'd still like to

QTT is now "TSV8", but it's not implemented yet - https://www.oilshell.org/release/0.20.0/doc/j8-notation.html

However we did implement the string notation, so that's some progress

This is not on the table for

• Minimal YSH That's Pretty Stable (list of issues) #1834

So it will almost certainly not happen this year, unless someone wants to work on it

It could also be "punted" outside the project like the shell GUI via the FANOS protocol

https://www.oilshell.org/release/0.20.0/doc/headless.html

If we define a protocol, and a minimal demo to consume it, then we don't have to write it ourselves

So it could be something like $TSV8_PAGER or $PAGER8
