RtpPacketizationConfig not properly initialized

[fusionfoxy]

The RtpPacketizer takes a RtpPacketizationConfig when created. After creation, this config must have the playoutDelayId initialized manually eg.:

        auto rtpConf_ = std::make_shared<rtc::RtpPacketizationConfig>(42, "foo", 96, 90000);
        rtpConf_->playoutDelayId = 0;

Otherwise, valgrind will complain about a Conditional jump or move depends on uninitialised value at

==48363==    at 0x312384: rtc::RtpPacketizer::packetize(std::shared_ptr<std::vector<std::byte, std::allocator<std::byte> > >, bool) (rtppacketizer.cpp:34)

I would expect the config class to initialize this value automatically.

Related to #1152

I'll push a fix.
