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.
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.
Remove the Addresser type. It isn't really necessary (the Address type
can change between OSes) and makes it difficult to fix a heap allocation
in interrupts (on the Nordic SoftDevices).
This is a backwards incompatible change, but only programs that use
SetConnectHandler should notice this.
This is necessary when connecting to a device when using the SoftDevice.
The information is not set on Linux and Windows and is ignored on those
platform when connecting.
