Fix wheel relocation issues (#2777)

* [DEBUG] Check wheel relocation issues

* Call delocate on Mac

* Use yum instead of conda

* Do not copy ffmpeg dylibs

* Linux dry run

* Do not download FFmpeg on Mac

* Install bzip2

* Restore FFmpeg on Windows

* Remove ffmpeg temporarily

* Do not remove dependencies

* Disable FFmpeg temporarily on Linux wheels

* Test relocation in Linux

* Add docstring

* Call relocation script

* Minor error correction

* Import auditwheel only on Linux

* Restore ffmpeg again on Windows

* Return *device

* Try fix Windows

* Fix clang-format

* Start windows patchwork

* Copy all DLLs

* Disable FFmpeg on Windows for now

* Bugfix
