Oops; Forgot to bump cligen with -u flag to nrel.

But don't worry - I added upDeps = true to ~/.config/nrel to avoid this in the future. ;-)

Modernize (& rename) `nio query`

Also some exception raising code clean-ups & help updates.

Also include cligen/mergeCfgEnv for CLuser tunability for utils/ programs.

Fix a style error & qualify stdlib imports with std/

Subject says it all on this one.

Make compile-able with stricter style

hint:name:on styleCheck=usages detected some internal style variation.

Minor fix to C program c2dsv.c; No Nim change

Just move a block of code to after the declaration section for pre-C99 C compilers.
(Also, cligen dep version update.)

Remove all remaining catz stuff, now in bu/

Minor bump since removal is kind of a big-ish change even though the CLI utility is in bu/ with many others.

A few fixes & add `nio widen`

Add nio widen to selectively widen (or narrow!) fields/columns. See doc comment for details.

A few fixes:

• Make ordinary file IO append by default.
• Do not leak open files in nio rip, though as a command that may never matter.
• work around a few glitches in Nim-devel

Bump cligen dep for new LC_PM

.. and re-phrase some documentation.

Add utils/nsv

Removed from the new bu/align was the old -W feature to generate parsing schemas which was helpful for a more manual nio inferT or just assessing some input files. The new utils/nsv replaces that functionality much more simply (with a little extra output, actually).

Also try to improve some docs a little.

Bug fix & add nio load1 --delim

Fix a couple range check bugs from @Vindaar and add --delim to nio load1.
