Move base plots to Python_Toolkit

[Tom-Kingstone]

NOTE: Depends on BHoM/Python_Toolkit#147

Issues addressed by this PR

Closes #206

Base plots and helper/utility methods have been moved to Python_Toolkit (see the linked PR at the top)
References to python_toolkit have been made where utility and helper methods have been moved, so that the rest of the toolkit and any user scripts do not break, though plots marked private that were moved will have been updated to python_toolkit.plot.<name-of-plot> and no longer marked as private.

e.g.
from ladybugtools_toolkit.plot._heatmap import heatmap
would become
from python_toolkit.plot.heatmap import heatmap

Test files

run the python unit tests to check that nothing is broken.

Changelog

• Moved python base plot types and some utility methods, see changelog for Python_Toolkit for more information.
