enh: replace unix2dos with sed

[Alexandr-Solovev]

Summary

Replaced usage of unix2dos with sed to remove an external dependency.

Details

The original script relied on dos2unix, which is not always available in all environments by default. This change replaces it with a sed command that achieves the same result (removing carriage return characters), thus improving portability and reducing setup requirements.

Changes

• Replaced unix2dos
• Removed the dependency on the unix2dos utility

Motivation

Minimize external dependencies and ensure better cross-platform compatibility.

Do we need to worry about it has to work on other systems like macos(some of the sed arg is not supported I think) ?

[david-cortes-intel]

OneDAL currently does not support macOS so no need to worry about it.

Sed is part of most coreutils out there (like GNUs) and is required by POSIX, so even if it doesn't come out of the box on macOS (although I'm pretty sure it does), it can be installed easily afterwards.

[david-cortes-intel]

Sorry, I think I misread it: yes, some arguments might indeed be GNU-specific extensions. This needs to be documented.

@Alexandr-Solovev Could you please add a note that this requires the GNU variant of sed if that's the case?

[Alexandr-Solovev]

Its implemented only for if $(OS_is_win), so, I think its not necessary to think about other system support

[david-cortes-intel]

@Alexandr-Solovev I think it's still theoretically possible to install non-GNU sed variants on windows.

[Vika-F]

I think msys2 uses GNU sed.

@Alexandr-Solovev Could you please remove the dos2unix requirement and instructions from the INSTALL.md file?
