ESPresense

• Fix errant voltage reporting

• Fingerprints are now 3 tier: primary ids > publicMac > secondard ids. A single mac can have multiple advertisements sent (especially certain beacons). So it might take a few packets before the id settles into the correct one.
• Volts and temperature are now reported from Eddystone TLM advertisements
• Names should show up more reliably now as well

Ntp wasn't used yet, so this will fix those who deny the internet...

• More changes to fingerprinting, id will be different if the device is sonos or samsung. Those instead of saying md: now use the manufacture name (samsung or sonos) as the prefix with the mac at the end
• Windows 10 we fingerprint as microsoft:<last 23 bytes in hex of manufacture data>. See https://petsymposium.org/2019/files/papers/issue3/popets-2019-0036.pdf for why, still not useful for a consistent fingerprint

Fixes #20

• Prefer mac address as ID if we have a static MAC and only md fingerprint
• Breaking: If you're using a md:: fingerprint, verify that it hasn't switched to the mac

Added support for clearing wifi setting via button on DevKit (as long as it's on GPIO15), use the esp32 flavor

• Fix fingerprinting of udm-pro
• Fix semaphore error

Go back to active scanning by default (so we can get the names of things)
Send telemetry only every 15s
