Vendor-specific command support on CMSIS-DAP probes

[mjakovlevs]

We would like to use pyOCD for flashing/debugging/testing but would also require controlling our customized CMSIS-DAP probe by using vendor-specific commands, and currently I don't see a way of doing that with pyOCD. Could you tell me if there is such functionality available, or is planned to be added? Any suggestions would be appreciated.
Thank you.
