I can't find anything that says the service UUID can also be a company
UUID (though the UUID number ranges don't overlap, so it could be
possible). Maybe I'm wrong, considering the size of the Bluetooth
specification I could easily have missed something.
This version fixes an error that leaked Go pointers to the WinRT runtime
causing random access violation errors (0xc0000005) whenver these
pointers where freed or moved by Go's GC. For more info checkout
saltosystems/winrt-go#94.

This was my attempt to figure out why scanning doesn't work on my
system. Sadly it still doesn't work, but at least I know there's no
error in this place.
(Note: I'm doing this on Windows ARM in a VM, so it's a rather special
setup).
* gap: fix comment
* gap: expose ServiceData() in AdvertisementFields
* macos: include ServiceData in AdvertisementFields
* gap/linux: include ServiceData in AdvertisementFields
* gap: add unimplemented ServiceData() to raw advertisement
* added ServiceData advertising element also to the sending pieces
* more explicitly use the ad element type ids
* added a test case for ServiceData
* linux: added ServiceData advertising element
* sd: fix: handle no servicedata present
* linux: bluez uses string uuids for service data
* linux: fix: correct datatype for advertise with ServiceData
* uuid: add 32-Bit functions
* ServiceData now also uses a slice instead of a map as in #244
* Revert unnessesary changes
* formatting
* remove extra check

This is a breaking change, but I believe it is necessary for
correctness. Because maps have an undefined iteration order, the actual
advertised packet could change each time which I think is a bad thing.
In addition to that, using a slice should be much more lightweight than
using a map.
I've also added some tests (that should have been there in the first
place) and added some manufacturer data to the advertisement example.
Furthermore, I've optimized the code that constructs manufacturer data
for raw advertisement payloads, it should now be entirely free of heap
allocations.
- add l2cap signaling support
- implement evtNumCompPkts to count in-flight packets
- correct implementation for WriteWithoutReponse
- speed up time waiting for hardware
- corrections to MTU exchange

- correctly return from read requests instead of returning spurious error
- move some steps previously being done during Configure() into Start() where they more
correctly belonged.
- use advertising display name as the correct default value for the generic access characteristic.
- speed up the polling for new notifications for Centrals

This adds support for the "connection supervision timeout", basically
the connection timeout while the connection is active (as opposed to
while connecting).
This allows changing the connection latency, slave latency, and
connection timeout of an active connection - whether in the central or
peripheral role. This is especially helpful on battery operated BLE
devices that don't have a lot of power and need to lower the connection
latency for improved speed. It might also be useful for devices that
need high speed, as the defaults might be too low.
The break statement didn't actually break the for loop, it just exited
the switch case.
Discovered because VS Code flagged the code after the loop as dead code.
This is unnecessary because the values are passed by value in other
cases, and can in some cases lead to more (heap or stack) allocation
than is necessary.
