Add support for ATmegaxx5/xx50 and ATmegaxx9/xx90 chip families

[MCUdude]

The latest version of MegaCore, v2.2.0 adds support for the ATmega165, ATmega169, ATmega325, ATmega329, ATmega645, ATmega649, ATmega3250, ATmega3290, ATmega6450 and ATmega6490.

This PR adds manifest files for all these. The chips also have full bootloader support through MegaCore through the existing bootloader.py script.

Hi!

Is there any ETA when this will be merged? Also @MCUdude do you have any estimate on when you will update the platformio/framework-arduino-avr-megacore package to v2.2.0?

@shawly this is done by the PlatformIO team (usually @valeros), not me. I don't see why this PR can't be merged as it is though.

That was fast!

Oh I thought you were maintaining the package since you were listed as Author

In that case I guess I'll just have to be patient. Thanks for the quick response!

I was already on my computer and got an email notofication 🙂

PlatformIO Registry is relatively new, and my Arduino cores were added before PIO registry existed. It would be great if I could just update the PIO registry every time I release a new version, but previously it was something the PIO team had to do, which tends to slow things down a bit. For instance, I'd really like them to bundle Avrdude 7.0 which brings a bunch of new features and improvements, but I've not gotten any response yet.

@valeros I've fixed an issue with the ATmega165/169, and this is ready to be merged!

Many thanks for the PR, merged!
