minor espflash command update

[Ricardicus]

Minor update to the espflash save-image command,

I got this error:

$ cargo espflash save-image --merge ESP32 outfile.bin --release
error: Found argument 'outfile.bin' which wasn't expected, or isn't valid in this context

Usage: cargo espflash save-image [OPTIONS] --chip <CHIP> <FILE>

For more information try '--help'

They might have changed so that --chip is needed and ESP in capital letters wasn't working for me.

Which version of cargo-espflash are you using?

[Ricardicus]

I am using cargo-espflash-espflash 2.0.0-rc.3 , seems to be the latest and greatest:

The book commands are using espflash and cargo-espflash 1 since 2.0 hasn't been officially released (still a release candidate). Once 2.0 is released, we will update all the espflash commands in the book, see #50.

Ok! I got espflash from following the guide. I just did cargo install espflash. Strange that I got a release candidate directly from cargo.. anyways! Maybe this can be included in that update

LGMT! Thanks for the contribution. Now that espflash 2.0.0 has been released, we can merge it!
