Add 921600 baudrate option.

[BrianPugh]

I flashed the firmware here and was unable to use ember-zli until I added a 921600 baudrate option. Then restoring tokens seemed to work fine.

Related note: it seems like I'm unable to use any online updaters once flashing the 921600 firmware; do you have any suggestions on how I can now flash firmware to this device?

@Nerivec I know , you have reservations about high speed, but I also use the same patch. And, likely. will keep maintaining high-speed versions of firmware. So, probably it is time to add option to ember-zli :)

if anyone needs anecdotal evidence; i always use 921600 speed with my esp32 projects :P. In my experience it's the fastest reliable speed.

Thanks!

I published a new release. Should allow interacting with the stack and flashing 😉

For the online flashers, they likely need an update same as this. Might need an update in universal-silabs-flasher too though (which is what online flashers use).

I think people, who will use not-mainstream 921600 builds, are people who know what they are doing, so, no need to worry about online flashers, but updating universal-silabs-flasher could be a good idea though. @BrianPugh can you also make PR for that one?
