uuid: Add UUID IsIn

[deadprogram]

This PR adds a function IsIn() to UUID which is basically the same as the shortUUID already has.

Why would one need this? What is the use case?

[deadprogram]

Needed for here https://github.com/tinygo-org/bluetooth/blob/nina-ble/gattc_ninafw.go#L73 and here https://github.com/tinygo-org/bluetooth/blob/nina-ble/gattc_ninafw.go#L168

slices.Contains() is too heavy for embedded, I suppose?

[ysoldak]

I don't feel good about this is general.
Feels unnecessary to extend API with some function that does not really belong to UUID, tbh.

[deadprogram]

I pretty much copied the existing implementation from here https://github.com/tinygo-org/bluetooth/blob/release/uuid_sd.go#L35-L43

I'd be fine with this as an unexported method. I'm not so convinced a method like this needs to be part of the public API: it provides very little value but does add clutter.
Note that the other IsIn is also unexported (because shortUUID is not part of the public API).

I did not notice that. I will move the implementation into uuid_ninafw.go to match that.

Now closing.
