#13380 closed Patch - Bug Fix (fixed)

DVB-T2 also needs channel_timeout increase for SDT

Description

DVB-T2 tuners also need a timeout large enough to catch the SDTs and the NIT just like DVB-C and DVB-T tuners.

In channelscanner.cpp, starting at line 439, there is a bit of code that increases the channel_timeout from the user-selected value to 7000 milliseconds if the user had selected a smaller value.
This is done for DVB-T tuners (sub_type OFDM) but not for DVB-T2 tuners who have sub_type DVB_T2.

The attached patch does add sub_type DVB_T2.

N.B. I found this when I saw different results from a channelscan of the local DVB-T signal with a new DVB-T2 tuner (Mygica T230) compared with an older DVB-T tuner (KNC-One).
