* fix: Do not create command prompt window on subcmd
Patches files from abandoned libraries are located and updated in
src/qt/helpers/vendored with modified sections labeld PATCHED. A wrapper
around subprocess.Popen automatically sets the creation flag to no
window on windows.
* fix: Replace Popen in mediainfo_json decoder
* fixup: Pipe stdin to stdin
* chore: Exclude vendored dir from tooling checks
* suppress mypy warnings
