[IMP] Added the ability to print the inverse dependency tree

[alexandregaldeano]

In our codebase we needed to know which modules were the most depended on.

So, here it is, the inverse dependency tree, where:

account (13.0+c)
└── c (no version)
    └── a (13.0.1.0.0)

Reads "account is a dependence of c, and c is a dependence of a".

Changes made:

• Added the --inverse option to the tree command
• Added the parents field in the tree.Node class, which is populated in the tree.tree_command.add function
• The parents field is used instead of the children field in the tree.Node.print method when in inverse mode

Nice one ;)

Technically Code looks good to me !

Thanks @alexandregaldeano. Can you rebase and add a news/75.feature file with a short changelog entry?

I plan a release soon to fix Odoo 19 support (#80).

@sbidoul noted, I try to do it by the end of the week 😃

@sbidoul I updated my branch foodles-tech:agaldeano/inverse-tree to acsone:main instead of updating foodles-tech:main which had the effect to drop my commit and close this PR 😬
Could you please reapprove the test workflow? 🙏
