use jstrdecode, removed unicode-fix.sed & unicode-chk.sh

Use ``jstrdecode(1)` to decode certain JSON strings,
such as "Full Name", "Abstract", "Award" and "Organization".

We now rely on a correctly decoding `jstrdecode(1)`.  The bin tools
now rely on `jstrdecode` with the following version or later:

>   jstrdecode version: 1.0.6 2024-10-08
>   JSON parser version: 1.1.7 2024-10-08

Removed `bin/unicode-fix.sed` and `bin/unicode-chk.sh`.
Removed `make unicode_chk`.

Fixed a few rule dependencies on `Makefile`.

Added information about `bin/jval-wrapper.sh` in `bin/README.md`.
