match(scan_data) should return True if scan_data is from the device you're looking for.
If no match function is provided, it is treated as always returning True (you want
to see all devices that respond within duration).
scan_data is a dict mapping description to value, unless match_scan_entry is True
in which case scan_data is a btle ScanEntry object.
Duration is how many seconds to scan before returning.
If just_one is False, scans for the full duration and then
returns a list of matching ScanEntry objects. (https://ianharvey.github.io/bluepy-doc/scanentry.html)
If just_one is True, this returns the first match immediately (no list)
or None after full duration timeout.
Note (match==None and just_one==True) results in just the first device
to respond being immediately returned.
