Fix some cc608 field number handling.  Refs #11899.

More accurately decodes CEA-608 captions encoded in SCTE-20 user data.
  * Field number 3 is merged with field number 1 instead of 2.
  * Data in field number 3 is not rejected.
  * Field numbers 1 and 2 are then swapped if top_field_first is false.
These changes are based on the SCTE 20 handling code from ccextractor.

Use Live TV order for the card list.

In many cases, the list of available cards was being returned in card
ID order, when it would be more appropriate (and correct) to use the
Live TV order.
Allow Live TV to be entered from the top-level Program Guide.

This allows the user to start Live TV on a specific channel from the
Program Guide grid.  Otherwise, the user needs to wait for Live TV to
start and tune the initial channel, then find the channel actually
wanted, and wait for it to be tuned.  This also provides a workaround
when the default initial channel is untunable for some reason.

Currently, if the desired channel is not tunable (e.g., all capable
recorders are already busy), it will fail.
