[brentru]

This pull request:

• Refactors the TinyUSB Filesystem's initialization routine
  • Addresses a bug where a filesystem created by WipperSnapper on the first run won't mount properly, by validating the fatFS after creation.
    • Addresses issues with hardware using the TinyUF2 bootloader instead of CircuitPython bootloader
  • Creates empty files on the FS to avoid macOS indexing
  • Hardware will now blink yellow continuously, instead of once, if there is an issue with the secrets.json file or if the user needs to interact with the WIPPER USB drive.
  • status pixel brightness reduced to 5%
• digitalio, analogio, statusled have been moved to components/componentname/src
• Bumps beta to version 8
