(#66) Implement BLE using bless

[WouterJD]

bless is a python library that enables python programs to create a BLE Service.

For FortiusAnt that means a FitnessMachineService FTMS.
This was implemented using node to circumvent the lack of a python library.

Notes how to test:

• Use the Implement-BLE-using-bless branch
• Execute pip install bless
• Specify -bb (instead of -b) to select the bless library instead of node.js (e.g. FortiusAnt (gui, autostart, BLESS).bat)
• Take care that on Windows a BLE-5 dongle must be present, the native windows driver is OK (no zadig required)
• Other platforms not yet tested, due to absence of test-hardware - being ordered :-)

Related changes:

• Debugging with -d became too complex, being numeric. Now specify -d CEWIDbpjmuafA (b=ble, u=usb, D=DEBUG)
• When standard python logging is selected (CEWID for Critical, Error, Warning, Info, Debug) then the logging library is used.

Current status:

• FortiusAnt -bb works with the bless library; NodeJs no longer required
• Tested with Trainer Road and Rouvy on android and FortiusAnt on Windows/Raspberry

Dependency:

• Windows 10 requires BLE/5 dongle

Installation:

• check requirements.txt
• On raspberry run 9_GrantAccessToBluetoothForBless.sh (modified dd. april 7th)

Test

• run bleBless.py, which starts a simulated FTMS OR run FortiusAnt -a -g -bb -s (simulator)
• run bleBleak.py, which simulates a CTP

Succes!

I have the impression BLE/bless implementation is now done.
Unfortunately, you will see the BLE-address in Zwift/Rouvy/TrainerRoad when FortiusAnt is runnning on raspberry and the windows-hostname when running on Windows 10. This is caused by the underlaying libraries and I cannot solve it.

Please let me know; ready for integration in Master

Verion number set to 6.4. Manual updated. Minor modifications. See wiki for solved issues.

Using the bless/development branch; the BLE implementation now works on Raspberry and Windows.
As soon as @kevincar has merged development, I can merge as well.
