CompatHelper: add new compat entry for "IntervalTrees" at version "1.0"

[github-actions]

This pull request sets the compat entry for the IntervalTrees package to 1.0.

This is a brand new compat entry. Previously, you did not have a compat entry for the IntervalTrees package.

Note: I have not tested your package with this new compat entry. It is your responsibility to make sure that your package tests pass before you merge this pull request. Note: Consider tagging a patch release immediately after merging this PR, as downstream packages may depend on this for tests to pass.
