Remove binary info header, was crashing picotool

[earlephilhower]

Because OTA has changed the flash map from standard, picotool ends up
crashing or hanging while trying to operate on the current built files.

Remove the binary_info calls and structures completely to avoid any
issue.

Fixes #803

Sorry it took a while for me to work out how to get that test release into platform IO. I'm sure that there must be an easier way but in the end I had to use command line git.

cd $home/.platformio/packages/framework-arduinopico
git reset --hard origin/noinfo

Which seems to do the trick from what I could tell of the files vs the changes logged int github. I seem to remember reading something about adding @ branch at the end of the platformio entry but it didn't seem to work for the board_build.core entry.

I removed the "upload_protocol = mbed" from platformio.ini. Did a clean and rebuild.
Then I reset a rpi pico to an old version uf2 firmware using bootsel/copy file. Then finally tried that demo program again with all Serial operation commented out. Uploaded multiple times without any problems!!! Hurrah!

Well done that was an impressive turn around.

For for completeness I did it again with the Serial commands uncommented. Again, all good.

Thanks for the feedback. I'll do a point release tomorrow with this, since P.IO uploads seem busted now...
