Add proper implementation for BDSBAS

[Narugakuruga]

Add PNR 130, 143, 144 to carrier frequency test.
Add sky view flags using existing asset.
Update SbasType and string to match names. SNAS only exist in very old press release. So rename to BDSBAS now.

Hopefully it won't affect database too much. There's 20 records of "SNAS" right now. But the signal is marked as "testing, do not use" anyway. I wonder why these device is using them

@barbeau Glad to have your review Mr barbeau! I would like to know what went wrong with the CI

[barbeau]

@Narugakuruga you should be able to click through on the CI link that failed, and then just scrolled at the bottom of the CI log. It should show what errors prevented the build from completing. If you take a look and can't see the problem let me know and I'll take a closer look.

Sorry, I was trying to label the sbas as B2a, But the code is out putting L5. Can you please help me check what is wrong? I think I must miss something.
