ESP32-S2 I2C Scan Fails on Beta 96, 97, but 95 is okay

[tyeth]

Scan fails with busy bus message, UI/web shows scan complete but empty

Noting that this does not happen on Beta 95 downwards, only beta 96+

linking this draft PR which doesn't properly solve the issue at source, but adds more logging and retries to at least let the scan continue:
#710

This should be resolved as part of v98
