Bluetooth scales library for ESP on Arduino Framework

This library defines3 main abstract concepts:

• A RemoteScales which is used as a common interface to connect to scales, retrieve their weight and tare. It also supports a callback that is triggered when a new weight is received.
• A RemoteScalesScanner which is used to scan for RemoteScales instances that are supported, and
• A RemoteScalesPluginRegistry which holds all the scales that are supported by the library.

This allows for easy extention of the library for more bluetooth enabled scales.

Currently implemented scales

• Acaia Lunar - [Tested]
• Acaia Pearl - [Tested]
• Bookoo Themis - [Tested]

There is a big possibility other acaia models work out of the box as well but thye have not ben tested!

How do implement new scales

We can do this either in this repo or in a separate repo. In both cases we need to:

1. Create a class for the new Scales (i.e. AcaiaScales) that implements the protocol of the scales and extends RemoteScales. This is 99.9% of the work as it involves reverse engineering or reading the datasheet of the scales and implementing it accordingly.
2. Create a plugin (i.e. AcaiaScalesPlugin) that extends RemoteScalesPlugin and implement an apply() method which should register the plugin to the RemoteScalesPluginRegistry singleton.
3. Import your new library together with the remote_scales library and apply your plugin (i.e. MyScalesPlugin::apply()) during the initialisaion phase.
