Enforce branch column order and colors

First of all, thank you for the great project!

Currently the order of branch columns is determined by which branch comes first in commit list:

export class GraphColumns<TNode> {
  private branches: Set<Branch["name"]> = new Set();

  public constructor(commits: Array<Commit<TNode>>) {
    commits.forEach((commit) => this.branches.add(commit.branchToDisplay));
  }
// ...
}

My app has an UI which hides/shows branches based on user requests by filtering commits which get imported to gitgraph, and arbitrarily changing branch order and colors become confusing for users. I’d like to have master branch always having column index 0, first selected branch having column index 1, second branch having column index 2, … regardless of which commit comes first in the log.

What would be the easiest way to accomplish this?

Thanks for your contribution @haizz 👋

As mentioned in the PR: I simply refactor the name to be more explicit. I went for the semantics of Array.prototype.sort(), thus I called it CompareBranchesOrder instead of BranchesOrderFunction.

I published v1.1.0-2 of @gitgraph/react & @gitgraph/core that contains the change. Let’s know if you find some issues with different ordering of branches.
