Code polishing for unifying code of different bars and spinner

[rlalik]

The code of four progress classes was polished:

• headers were sorted,
• Settings tuple was sorted that common options occupy more-less same positions in the tuple - it allows to easier find common pattern with diff between files,
• signatures for same like functions were unified,
• some redundant pieces of code were removed,
• whole code was formatted with clang-format-20 with column width set at 100.

What I can do is I can squash commits to a single one.
I can also reformat with clang-format other files of the project which I didn't touch yet (to make changes as small as possible). One uses Windows end-line markers which could be fixed as well).

Well, I am happy that you like this. What I did now is, I polished all the remaining files - mainly run clang-format on them. I also fixed the clang-format.bash script. I also regenerated the single_header file.

I would recommend to add calling clang-format.bash and then to create single_header file into workflow.

It seems that there were dos files. If you do development on windows, worth to fix file endings. I can include a simple script using dos2unix program to fix the files if you like. It then could be then also part of the workflow after some editing on windows (of course will not work on windows).
