This PR adds support for the new iter package in go1.23 allowing a for range loop to be used with the ordered maps improving devex

This is great, thank you!

Suggested renaming a couple funcs, would be great to mention that in the README as well?

Ideally we'd want iterators from newest pairs too?

[TristanSpeakEasy]

Thanks @wk8 I chose to match the naming of the map.All, map.Keys and map.Values function in the stdlib as it would help with discovery but let me know if you would like me to definitely changes these to the suggested names.

I can also update the readme

Actually in light of this I changes all the names and added the new methods

[TristanSpeakEasy]

okay have address the feedback plus added a utility From method for making copies easily using the iterators

[TristanSpeakEasy]
