Add framework choice to board

Hello everyone!

How to add mbed framework option for STM32F103CB** microcontrollers?

It is a microcontroller on MapleMini dev.board, and is easily usable with mbed framework:

But now there are only Arduino, STM32Cube and libOpenCM3 framework options for this microcontoller.

I already reported this ~4 months ago: Add mbed framework to STM32F103CB · Issue #98 · platformio/platform-ststm32 · GitHub

The STM32F103CB is the 128K flash version of the STM32F103C8 chip (64K flash) wh…ich also powers the bluepill board. (On [most bluepill boards](http://wiki.stm32duino.com/index.php?title=Blue_Pill#128_KB_flash_on_C8_version) you can actually access the whole 128K of flash as if it were a CB version.) So if the board `genericSTM32F103C8` supports mbed, the CB version with just the bigger flash should be supported, too. It is also confusing that the board "bluepill_f103c8" (doesn't support mbed) is different from "genericSTM32F103C8" (supports mbed) although they are listed to have the exact same MCU. I tried adding "mbed" to the list of frameworks myself in the boards/genericSTM32F103CB.json file which resulted in PIO complaining about a missing config file. After going to `.platformio\packages\framework-mbed\platformio` and following the instructions in the `README.txt` the command `tox` failed with error ``` Current target UBLOX_EVA_NINA Current target VBLUNO51_OTA Traceback (most recent call last): File "piombedgenerator/main.py", line 268, in <module> sys_exit(main()) File "piombedgenerator/main.py", line 204, in main toolchain.config.load_resources(framework_resources) File "..\tools\config\__init__.py", line 937, in load_resources features = set(self.get_features()) File "..\tools\config\__init__.py", line 891, in get_features params, _ = self.get_config_data() File "..\tools\config\__init__.py", line 819, in get_config_data all_params = self.get_target_config_data() File "..\tools\config\__init__.py", line 765, in get_target_config_data ConfigParameter.get_display_name(tname, "target"))) tools.config.ConfigException: Attempt to override undefined parameter 'uart_hwfc' in 'target:VBLUNO51_OTA' ERROR: InvocationError: 'C:\\Users\\Maxi\\.platformio\\packages\\framework-mbed\\platformio\\.tox\\python\\Scripts\\python.EXE piombedgenerator/main.py' ``` so I hit a road-block there.

Yes, it works.

Thanks!
