Fixing bug initializing the ManufacturerDataMask Bytes of the DataMask are initialised with 0b00000001 instead of 0b11111111, hence only the least significant bits of the filter and the result set are being compared. Effectively the FilterMask is just an even/odd filter for the selected bytes. Also added the iBeacon type identifier (0x02) as well as length byte (0x21) to the filter mask. I understand this is done in the onScanResult method @ScannerScanCallback, however, as type byte and length are fixed this will reduce

Bytes of the DataMask are initialised with 0b00000001 instead of
0b11111111, hence only the least significant bit of the DataMask and the
result data are being compared. Effectively the current FilterMask is just an
even/odd filter for the selected bytes.
Also added the iBeacon type identifier (0x02) as well as length byte
(0x21) to the filter mask. I understand this is done in the
onScanResult method @ScannerScanCallback, however, as type byte and
length are fixed this will reduce unnecessary callbacks.
