Very minimal change to config file finding

See RELEASE_NOTES.md and git log -p. Really should be just an internal simplification, but I wanted to make this its own release just in case.

Very minor new feature for dispatchMulti

Add ability for both multi-cmd -h & multi-cmd h to interpolate in doc from the X in ["multi", doc=X] fragment. This helps to explain global options, available from the recent Vars feature (and also to describe the overall program).

Also make test.sh/GNUmakefile more environment-portable by turning off --styleCheck

Better fix for `cligen/statx` & style fix

Those two things are about it.

Fix a few bugs/compatibility issues

• Fix generic instantiations of doArgParse (#233) on newer Nim compilers courtesy of @metagn

• Make misc lib code compile under --hint[Name]=on --styleCheck=usages --styleCheck=error

• Vaguely robust (if information dropping) solution to Alhadis/OSC8-Adoption#13 (comment)

Make things easier for system package managers

By including a very simple make/gmake install with a re-targetable destdir.

Nim-devel is moving to better `hash(openArray[byte])` ..

.. and a very slow (several to order of magnitude slower even on short strings) hashData (OG string hasher, actually).

So, it seems important enough to warrant punching a release changing that default in cligen/mslice.hash(MSlice) which is the only change of this release.

Very minor bugfix release

To fix two undesired output format cligen/strUt.ecvt bugs (and make that test suite not super slow by default).

Extend PL<->CLI to include var binding / dispatchMulti global options

The main new feature is binding an outer scope variable to a CLI option which creates a slight backward incompatibility (a new argument after other ident string args positional, suppress, implicitDefault, not at the very end of the list). RELEASE_NOTES.md, test/Vars.nim, & test/FullyAutoMulti.nim go into more detail, but this can be used for a several-times requested feature of global options in dispatchMulti commands. The new in-the-middle argument should only impact code that fully wraps dispatch/dispatchGen which may be none outside cligen.nim itself as anyone else is likely to use named parameters/keyword args for a 20-parameter call.

This release also fixes a bug and stray debug print in -d:cgCfgToml mode which alters the config file syntax of the [color] section. That also constitutes a minor mode-specific backward incompatibility. Together the two "maybe kinda breaking" induce a minor version bump.

This version also fixes several bugs:

• rare rounding bugs in fmtUncertain*
• cligen/dents bug related to lstats
  and adds a few small features:
• mslice.initSep grows an ability to not backslash-escape TAB, newline, and NUL
• Tiny MacroCallX API to make non-allocating tmpl renderers easy
• Add a low cost Nim Slice/HSlice -> MSlice converter so someMs[a..<b] works

Very small changes..mostly make CI green again..

..and suppress a warning and also add a little mslice.within API call.

Small release for new CL signal name parser & untest nimskull compat

Quoth Stan Lee: 'nuff said.
