Update tvtv.us_us-local.channels.xml

This intends to address #1075. I did not add channels that appear to relay national feeds 24/7.
Given that, I added WWAYDT1.us, WWAYDT2.us, WWAYDT3.us, WECTDT1.us, WBTWDT1.us, WBTWDT2.us, WPDEDT1.us, WPDEDT2.us, WPDEDT4.us, WSFXDT1.us, WMBFDT1.us, and WFXBDT1.us.
Since WHMC is South Carolina Educational Television, I added the SCETV Headquarters station's WRLKDT1.us, WRLKDT2.us, and WRLKDT3.us.

I added independent WILMLD1.us and the PBS North Carolina flagship digital channels that did not directly relay national feeds (WUNCDT1.us, WUNCDT3.us, and WUNCDT4.us).
