Scan by Organizationally Unique Identifier (OUI)

It would be nice to be able to scan with filters on OUI.

Here's how it would look like for the Xiaomi Mi Band:

return navigator.bluetooth.requestDevice({
  filters: [{ ouiData: [0x880F10] }] // Huami Information Technology Co.,Ltd.
}).then(device => { ... })

According to https://standards.ieee.org/develop/regauth/tut/eui.pdf and http://standards-oui.ieee.org/oui.txt

Where's the OUI in Bluetooth data? If it's in some of the advertising data, this is probably fine, but if it's in https://developer.bluetooth.org/gatt/characteristics/Pages/CharacteristicViewer.aspx?u=org.bluetooth.characteristic.system_id.xml, I believe it's too expensive to connect and gather that data while scanning.

According to http://git.kernel.org/cgit/bluetooth/bluez.git/tree/lib/bluetooth.c#n100, OUI is based on Bluetooth Address. For instance,

bluetooth address	OUI	Company Name
88:0F:10:9D:EB:42	88-0F-10	Huami Information Technology Co.,Ltd.

Hmm that's going to be tricky on Mac since they don't expose the address.

Yeah, and lots of devices use random addresses, without the APIs telling us that the addresses are random. I don't think we can practically filter scans by OUI.
