Build out support for PlatformIO

[nseidle]

I've never done it but if someone has the experience getting an platform into platformio I would love to work with them. Please let me know.

Hi, I wouldn't say I am experienced at development for PlatformIO but I have been playing with this: https://github.com/nigelb/platform-apollo3blue. It has not received a lot of testing because I ran into this issue: sparkfun/Arduino_Apollo3#94

Just curious of what the status is here? :)

Hi, I and have recently fixed a lot of bugs (in platform-apollo3blue) and got thing working pretty well so that the master can now build against both the v1.x.x and v2.x.x series of Arduino_Apollo3 (example). Now that I have identified (sparkfun/Apollo3_Uploader_SVL#4) and found a work around for (sparkfun/Apollo3_Uploader_SVL#6) my last remaining issue with uploading a firmware from Linux I think it is getting to the point where, soon, I can publish the apollo3blue platform to the PlatformIO repository.

For this to happen we need to sort out the following in Arduino_Apollo3:

1. Version bump the package.json of the 1.x.x series - Pull Request #437.
2. ~~Add a package.json for the v2.x.x series (I am happy to submit a pull request):~~ Pull Request #430 has been accepted.
3. With the release of PlatformIO 5 they removed the ability to point to other repositories for packages. What this means is that both versions of Arduino_Apollo3 will need to be published to PlatformIO repositories.

Just being curious: any progresses forward on this? I can personally install / tweak by hand things, but working with some students / other users who have difficulties getting the platformio package going and switching between core v1 and core v2 there.
