logrange

[mcabbott]

This adds https://github.com/JuliaLang/julia/pull/39071

Note that:

• The version check may need to change once backported to 1.11 branch
• Before Julia 1.9, it won't use TwicePrecision, as the necessary log/exp functions aren't defined. The result is slightly worse floating point accuracy.
• It doesn't print the same way, since there's a big messy print_range function (for LinRange) whose signature the PR widened.
• The docstrings don't show up in REPL help, I don't know why. Maybe that's true of all functions here. It means you can't see the notes about the above points.

I don't have the energy/enthusiasm to review this PR. Feel free to proceed without me.

The docstrings don't show up in REPL help, I don't know why. Maybe that's true of all functions here. It means you can't see the notes about the above points.

I think that's because they are inside the if, not at top level, so need an explicit @doc.

[mcabbott]

so need an eplicit @doc.

I've added this to all docstrings in the package, since none worked before. (Could be a separate PR but that's more hassle.)

If you include a version bump in Project.toml, we can tag a new version immediately after merge. Otherwise seems good to go.
