PRs from standard-version that could be brought in

[TimothyJones]

I've already merged and released all the easy PRs from standard-version. This issue is a list of all the PRs that could be accepted under the fork rationale, but that I felt needed a bit of work before merging. Discussion and PRs welcome.

• feat: lightweight tags is added as option conventional-changelog/standard-version#825 Adds the ability to use lightweight tags - it seems worth accepting, but I felt the documentation didn't describe the feature in a way that I understood.
• feat(bump): added filePath to writeVersion parameters conventional-changelog/standard-version#561 This improves the information that updaters recieve - I think this is a good idea, but it would be better long term if the third argument was a metadata object with a key of filePath instead of just the filename.
• feat: allow updater's readVersion and writeVersion to execute asynchronously conventional-changelog/standard-version#721 This brings in the ability to have async file updaters. This is definitely a good idea, it just needs tests with both async and non async file updaters.
• feat: allow the tag message to appear as the title of releases in change log conventional-changelog/standard-version#649 This adds the ability to have release titles. The changelog is included in the PR (which needs to be removed) and it needs documentation
• feat: add ability to supply a version to bump from conventional-changelog/standard-version#448 This adds the ability to source versions from information other than git tags - the name of the parameter needs updating, it needs tests, and it needs documentation

Closing this due to inactivity on the linked PRs - I'm assuming that they're niche cases that the authors don't need any more.

If anyone finds this and wants any of the linked features, please feel free to raise PRs (or open an issue) here.
