My ESP32-WROOM is sending some non-utf8 data just after reset, causing boot mode detection to fail. This commit uses `String::from_utf8_lossy` to ignore these bytes. Tested on macOS, boards: ESP32-WROOM-32, ESP32-WROOM-32D, ESP32-C3-MINI-1, ESP32-C3-12F.

Hello! Mind testing what's the behavior with esptool?
My reasoning behind not using _lossy was that it can lead to "unhelpful" error messages, using branch in the #570 scenario, results in:
[2024-02-05T10:08:48Z INFO ] Serial port: '/dev/ttyUSB0'
[2024-02-05T10:08:48Z INFO ] Connecting...
Connect attempt
[2024-02-05T10:08:48Z INFO ] Using flash stub
Error: espflash::timeout
× Error while connecting to device
╰─▶ Timeout while running command
This scenario is not common I'd say, but yet the error message is pretty confusing to the user.
