Ability to specify locale options for strings

[LinusU]

We have a lot of arrays that we are sorting before presenting to a user. Since it's a Swedish app we are using the following code:

lhs.localeCompare(rhs, 'sv-SE', { numeric: true, sensitivity: 'accent' })

It would be great if there was a way to pass these options into the localeCompare call inside sort-on.

If you have any input on how the api would look I'd be happy to submit a PR 🚀

Maybe a locales and localeOptions options where the latter is just passing through http://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl/Collator/Collator#options ?

Alternatively, move locales into the the localeOptions, but that may make it harder to document and type.
