Can't wake up from a button and detect which

[kobigurk]

I've seen both #21 and #26 that discussed this, but seems like there wasn't a solution there.

My findings meanwhile are:

• esp32-wroom-32 supports only ALL_LOW or ANY_HIGH, and doesn't support ANY_LOW - for ext1
• INPUT_PULLUP works, INPUT_PULLDOWN doesn't - which leaves buttons at an always-high state, so ANY_HIGH isn't suitable
• configuring multiple ext0 works, but then can't detect which button, since only ext1 supports that

Any ideas?
