Added cadence, speed and assistance level + new layout

[NicholasRasi]

Now it is possible to display:

• cadence
• speed
• assistance level

Wow this is awesome :) So cool that you worked out where those values are - makes me want to try it now! And I didn't even expect assistance level would be in there. A lot of people have been asking for cadence, so they will appreciate it :)

I'm not a GitHub expert, so I'll work out how to merge your work. And then make a new build for the Garmin App Store.

With these extra values, I'm wondering if it's possible to have 2 data fields (separate ones in the app store) - whether the Garmin device end, and the Shimano e-bike end can both handle 2 Bluetooth connections at once. Then it would be possible to display different data in each field. Might have to try it and see ...

:smile: thank you. Actually there are more information that you can get from the ble connection.

The data available from the 3 notifications are (at least):

• assistance mode
• current speed
• assistance level
• cadence
• traveling time
• traveling distance
• cumulative distance
• average speed
• maximum speed
• traveling ranges (eco, normal, high)

However, I don't think that other information are truly useful for the average user, but they are there.

This is possible because for example, with the Vivoactive 4 it is possible to add 2 fields on the same page. However I don't think is the best way to achieve a good result mainly because:

• users need to download and configure two apps
• energy waste due to multiple open connections.

I also tried to display the fields on multiple lines with a simple "\n" however it does not work.

I think that it would be better to use the complex data field, and display the 3 values vertically. However, it requires more efforts.

Changelog:

• added a new layout based on DataField. It is implemented using Dc (device context), computing the position of elements at runtime, because as far as I know layouts are more memory intensive and it easy to get a out of memory error.
• the user can now choose among 4 values. The value will be displayed only if not off. In this way the datafield can be used also with other datafields on the same page (e.g. as a single field) depending on the user's configuration.
• refactoring of the code: the BLE section was moved to another file
• added mockup BLE: it can be used to simulate the BLE connection (now it just return random values). It can be switched on setting to true the debugging variable
• the label was removed to simplify the layout

I've tested it with the simulator and a Vivoactive 4 and it seems to work.
