CHANGELOG.md does not adhere completely to the Keep A Changelog format

[LikeLakers2]

Hi! I was looking through some crates on crates.io, and I happened to chance upon the CHANGELOG.md file within this repository.

I noticed that it didn't quite adhere properly to the Keep A Changelog format - despite claiming otherwise in its opening lines. For example:

• The header is Change Log instead of Changelog (pedantic, I know, but it's good to be consistent c: )
• The 1.0.0 - 2023-??-?? is clearly representative of an Unreleased section - so it should be labeled as such.
• The various sections under each version ("Breaking Changes", "New Features", "Improvements", "Fixes") do not match the "Types of changes" that Keep A Changelog proposes to use.

To be clear, I'm being pedantic with all this. The changelog is actually fine as-is! Importantly, it's kept consistent, so it's not as if it's hard to read.

But if you'd allow me, I'd gladly go through and rewrite (or rather, rearrange) CHANGELOG.md to fix the things listed above. Would that be okay?

Sounds good to me. Seems like an easy to review PR (I love receiving those)

Okay! I'll start work on it sometime in the next couple days (currently working on my own projects and all).
