Set python3 option for console lexer

[AndrewSwann]

For python 3 code I can specify the lexer for verbatim environments as py3, but for console output I wish to use the pycon lexer with its python3=True option. Currently I see no mechanism to pass this option in pythontex to pygmatize, whereas minted has an option for this.

Here is a sample document where the highlighting of the @ operator in the console output is wrong.

\documentclass{article}

\usepackage{pythontex}
\setpythontexpyglexer[py]{py3}

\begin{document}

\begin{pyconsole}
print(sys.version)
import numpy as np
print(np.array([[1,0],[0,1]]) @ np.array([[0,1]])
\end{pyconsole}

\begin{pyverbatim}
print(sys.version)
import numpy as np
print(np.array([[1,0],[0,1]]) @ np.array([[0,1]])
\end{pyverbatim}

\end{document}

At this point, everything really should default to Python 3 compatibility. In the last commit, I've set pycon to use python3=True always and also changed the default Python lexer to python3. Adding support for setting arbitrary lexer options is more complicated given the current design, so I will look into that later.

Many thanks - this now works well for python3 which is what I am interested in. Andrew
