@vivek-anand-singh This PR cannot be accepted as is.

1. This PR also includes cusome-by. Please keep your PRs to only 1 feature. Multiple features should be split across separate PRs.
2. You added @stdlib/math/special/fibonacci-index, and not @stdlib/math/base/special/fibonacci-index. Adding the former is not what was requested.

[kgryte]

Please follow conventions elsewhere in the project. For submitting PRs, please see recent merged PRs for an idea of what is expected. Given that the intent was to add @stdlib/math/base/special/fibonacci-index, I suggest examining the PRs linked to #649.

[kgryte]

As #1756 has already been implemented in #2272, I will go ahead and close this PR. @vivek-anand-singh I suggest finding another issue to work on, perhaps asking on #649 where work is being tracked.

[vivek-anand-singh]

@kgryte, I deeply apologize for the mistakes in my PR.

For the first issue, I previously raised a PR on the cusome-by branch (PR #2661). When the second issue got assigned to me, I mistakenly assumed I was on the main branch and didn't switch branches. This oversight affected the PR, and I take full responsibility for it.

For the second issue, I overlooked the base folder, which I fully accept was my fault. I should have been more thorough in reviewing the project structure.

I sincerely apologize for any inconvenience caused. I genuinely want to learn from this experience and contribute positively to the organization in the future. I'm truly sorry for the oversight and would be grateful for another opportunity to make things right.
