Progressbar not shown when inserting/upserting jsonlines file

[MischaU8]

When inserting or upserting a jsonlines file, no progressbar is shown. Expected behavior is that, just like with .csv/.tsv files, also for a jsonlines file (--nl), unless --silent is provided, a progressbar is shown.

sql-utils upsert mydb.db posts posts.jl --nl --pk post_id
(silence)

Currently file_progress is only called within the tsv/csv logic, however I think it can be safely wrapped around all the all the input formats that use decoded: https://github.com/simonw/sqlite-utils/blob/main/sqlite_utils/cli.py#L963

A note from PR #486: #486 (comment)_

sqlite-utils insert /tmp/t3.db t /tmp/big.json 
  [####################################]  100%

This is actually not doing the right thing. The problem is that sqlite-utils doesn't include a streaming JSON parser, so it instead reads that entire JSON file into memory first (exhausting the progress bar to 100% instantly) and then does the rest of the work in-memory while the bar sticks at 100%.

I decided to land this anyway. If a streaming JSON parser is added later it will start to work.
