1. Update the API to accept the credentials on input instead of credential manager.
2. Update the test with values using the LDT encryption.
These changes allow us to have a more asynchronous implementaion.
When broadcasting we can:
1. Fetch the private credentials asynchronously.
2. Create the advertisement and start broadcasting when the credentials have been fetched.
When scanning we can:
1. Fetch public credentials asynchronously.
2. Start scanning for advertisements.
3. Update the decoder when new credentials are fetched.
