`BARCODE_PLAIN_HRT` option for `output_options` - for use primarily by ZXing-C++ but may be generally useful; centralize setting of HRT using new common `hrt_cpy_nochk()` etc. routines to ensure `text_length` always set PLESSEY: add show default check characters option CODE32: ignore `option_2` (check digit options) PZN: ignore `option_2` (check digit options) except when indicates PZN7 only DPD: exclude DEL from ident tag also out_maybe_mkdir: fix `utf8_to_wide()` return (Windows only) general: replace use of `strcpy()` etc. (except for test suite) with `memcpy()`, `hrt_()` etc. in lib & `cpy_str()` etc. in CLI & `cpy_bytearray_left()` in backend_qt clang-tidy: update README reflecting above backend_tcl: use sizeof(primary) to check length; tabs -> spaces general: various code fiddling docs: pandoc 3.6.2 -> 3.6.3
