This adds a separate opencv4_contrib package to manage
downloading/unpacking that repository. These extra modules
are useful for a lot of applications, but not necessary
for minimal installs, so they are all given dedicated Kconfig
options
It's important to note that the opencv4-contrib package
downloads extra source that is compiled as a part of
the opencv4 package. This is why it is a dependency
of opencv4, and not the other way around
