Confirming C6 can be made to work

Hi! Just wanted to confirm that I am able to get Bermuda working using my C6 boards (specifically, [these DFRobot boards](https://www.dfrobot.com/product-2778.html)), since that was [mentioned in the wiki as unverified](https://github.com/agittins/bermuda/wiki/ESPHome-Configurations#compatibility-of-esp32-chips). I had to use a newer version of esp-idf, even with the latest esphome, or I'd get compile errors. But with these versions it's good.

My data is pretty noisy with lots of gaps, but I read that's a common issue. I may need to play with the timings more. But it does technically work.

My relevant esphome config, mostly borrowed from the example C3 config (note, I might not need all those platformio overrides anymore, I haven't tested removing them recently):

```
esphome:
name: $devicename
friendly_name: $friendlyname
platformio_options:
board_build.f_cpu: 160000000L
board_build.f_flash: 80000000L
board_build.flash_size: 4MB
build_flags: "-DBOARD_HAS_PSRAM"
board_build.arduino.memory_type: qio_opi
