Add support for BDS B2b and IRNSS L1. And update signal detection to match the actual BDS

[Narugakuruga]

Add the ability to properly detect BDS B2b and IRNSS L1.

1. BDS "B2" is rename to "B2b", as B2I signal is marked as obsolete in official press release and due to the fact that they share the same frequency. I highly doubt any civilian device was meant to support B2I. More detail see Add support for Beidou-3 B2b signal #652

Source: http://www.beidou.gov.cn/yw/xwzx/201712/t20171226_11012.html

2. IRNSS L1 support, see Add support for NavIC L1 signal  #653.

3. Remove the code for "B1-2" signal. I think it's an out-of-date mistake. I have checked every website, paper, press there is no such signal.

4. Rename B1 and B3 to B1I and B3I to match the official name. (It's uppercase "i", not lowercase “L”)
   Maybe this will reduce user's confusion. as there are two B1 band.
   And yes B3I is not obsolete. It may be supported by consumer market one day.

And the precise frequency for B2b and E5b appear to be 1207.139970 MHz. But GPSTest already display E5b properly.
So I think it's fine.

@Narugakuruga Thanks for working on this! Looks like there are some failures on CI - https://github.com/barbeau/gpstest/actions/runs/6624229299/job/18020421843?pr=657:

Could you please take a look?

[Narugakuruga]

My apology 😀. I didn't know coding very much.
It should be fine now

[Narugakuruga]

I think it's ready now.
Would like to research how to add BDSBAS support too. But will be another day.

LGTM, thanks @Narugakuruga!

In GPS database, B2 was detected.
The previous code can detect B2b as "B2". At least it did work! So the new code should funtion normally too
