Refactor for atopile 0.11.6

[nickkrstevski]

Updating this project to use the latest syntax and best practices from 0.11.6.

I tried to ensure the layout didnt change, hopefully the functionality is identical.

• Removed footprints/ directory
• Used "ato create part" to pull all JLC components
• Deleted old floating footprints and .ato component files after ato creating parts for them
• Changes imports to match new parts/ filepaths
• Removed imports from generics/ and imported from standard library: Power -> ElectricPower etc
• Removed manually installed packages and used ato add <dependency> straight from packages website
• Left in some potentially unused imports like usb, xt-connectors, irlml5203, bzx384, XH_minus_2PS etc. Would delete if no plan to use them
• changed vcc -> hv, and gnd->lv
• used bridge connect where possible
• override net names example
