Handle Hiero API deprecated projectRoot methods

[dealmeida]

In Nuke 12, some methods of the API hiero.core are deprecated and will be removed. That's the case for Project.projectRoot() and Project.setProjectRoot()

This Pull Request proposes to handle these cases with wrapper methods that will call the API method recommended by Hiero
Documentation when the Nuke Major Version being used is superior or equal to 12.

@pscadding, @jfboismenu what do you think ?

Hi!
Does this mean that our Hiero integration is currently broken with Nuke 12? I find the wording from Foundry confusing. The methods are listed as part of the API but being removed?

Hello,

In 12.1 - the only minor version we've tested until now - the integration is not broken: there's this warning printed on terminal ([DEPRECATION WARNING] Project.setProjectRoot() will be removed in Nuke 12...) but the methods still work. We haven't tested the 12.2 version.

Hi,
I've just tested the same methods - projectRoot() and setProjectRoot() - with nuke 12.2v1 and they both work in spite of the warning messages.
