Change List<byte[]> storedDevicePublicKeys to IReadOnlyList<byte[]>

[joegoldman2]

Following #447, this PR changes List<byte[]> storedDevicePublicKeys to IReadOnlyList<byte[]>.

There is no impact on the demo website as the stored credential contains a List<byte[]> for the device's public keys, which is compatible with IReadOnlyList<byte[]>.

Line 51 in 5284757

public List<byte[]> DevicePublicKeys { get; set; }
