Transfer of PyImath history and source to Imath

[oxt3479]

Checks will fail due to the large addition of git history. Nevertheless, let this PR serve as a demonstration of intentions with the merging of the two repos (Imath/PyImath) and as a place to voice concerns.

With this initial implementation by default PyImath will not compile. This can be toggled using cmake from the command line:
% cmake $source_directory -DPYTHON=ON / -DPYTHON=OFF.

Out of curiosity, is this a roughly one year truncation of the history, or am I reading it wrong?

Out of curiosity, is this a roughly one year truncation of the history, or am I reading it wrong?

This should contain the entirety of the history of PyImath (93 commits). This was originally obtained by filtering OpenEXR's history based on commit directory. So no truncation was applied deliberately.
