While nice at first, this causes more issues than it's worth for
a slightly more pretty output.
Hiding information from developers is not a good idea, especially when
it comes to an often finicky programming step.
While in theory error output should be caught, there are enough
cases where the programmer will get stuck in a loop or require user
input that hiding programmer output by default is a bad idea.
When multiple debuggers are connected then pyocd shows an interactive
UI to select the user interface to flash, with python wrapper this
is lost.
Until a similar functionality is implemented with the wrapper disable
the programmer wrapper script when pyocd is used.
