tools/pyboard.py: Add parse kwarg to eval. 

This is useful when using pyboard.py as a library rather than at the
command line.

    pyb.eval("1+1") --> b"2"
    pyb.eval("{'a': '\x00'}") --> b"{'a': '\\x00'}"

Now you can also do

    pyb.eval("1+1", parse=True) --> 2
    pyb.eval("{'a': '\x00'}", parse=True) --> {'a': '\x00'}

This work was funded through GitHub Sponsors.
