Phase 3 of the GPS rework (#3220)

Browse Source 
* Portduino multiple logging levels

* Fixes based on GPSFan work

* Fix derped logic

* Correct size field for AID message

* Reformat to add comments, beginning of GPS rework

* Update PM2 message for Neo-6

* Correct ECO mode logic as ECO mode is only for Neo-6

* Cleanup ubx.h add a few more comments

* GPS rework, changes for M8 and stub for M10

* Add VALSET commands for u-blox M10 receivers

* Add VALSET commands for u-blox M10 receivers
tweak M8 commands
add comments for VALSET configuration commands

* Add commands to init M10 receivers,
tweak the M8 init sequence, this is a WIP as there are still some issues during init.
Add M10 version of PMREQ.

* Add wakeup source of uartrx to PMREQ_10
The M10 does not respond to commands when asleep,
may need to do this for the M8 as well

/*
Operational issues with the M10:
PowerSave doesn't work with SBAS, seems like you can have SBAS enabled, but it will never lock
onto the SBAS sats.
PowerSave doesn't work with BDS B1C, u-blox says use B1l instead.
BDS B1l cannot be enabled with BDS B1C or GLONASS L1OF, so GLONASS will work with B1C, but not B1l
So no powersave with GLONASS and BDS B1l enabled.
So disable GLONASS and use BDS B1l, which is part of the default M10 config.
GNSS configuration:
Default GNSS configuration is: GPS, Galileo, BDS B1l, with QZSS and SBAS enabled.
The PMREQ puts the receiver to sleep and wakeup re-acquires really fast and seems to not need
the PM config. Lets try without it.
PMREQ sort of works with SBAS, but the awake time is too short to re-acquire any SBAS sats.
The defination of "Got Fix" doesn't seem to include SBAS. Much more too this...
Even if it was, it can take minutes (up to 12.5),
even under good sat visability conditions to re-acquire the SBAS data.
Another effect fo the quick transition to sleep is that no other sats will be acquired so the
sat count will tend to remain at what the initial fix was.
*/
// GNSS disable SBAS as recommended by u-blox if using GNSS defaults and power save mode
