Fixes circular dependency issue by moving the version to a separate file

[reidsunderland]

pip couldn't install depedencies because sarracenia/init.py was importing them, and setup.py was importing sarracenia.

There might be better ways of doing this in newer versions of Python (>3.6), but this way seems to be common in packages like Paramiko, Requests, etc.

# When Sarracenia is installed, pip is aware of the version because it's set in setup.py
aspyras@srdev6:~/sr3$ pip3 show metpx-sr3

Please have a look at docs/Source/Contribution/Development.rst there is a release process documented there, that needs adjustment... have to change the French also.
