Enhancements

• CLIENT-6420 The static library dependencies are now embedded in libTwilioVoice.a
• The libboringssl.a library is now separated and shipped alongside the static library libTwilioVoice.a. Add -lboringssl in the Other Linker Flags to link the SDK properly.
• CLIENT-6438 Added customParameters property to TVOCancelledCallInvite.

Pass custom parameters in TwiML

        <Parameter name="caller_first_name" value="alice" />
        <Parameter name="caller_last_name" value="smith" />
