Accept a separators parameter

[klahnakoski]

The builtin Python JSON encoder accepts a separators parameter. Adding this to ultrajson can help with achieving byte-wise identical output with that encoder. This could help expose other bugs in the corner cases of encoding.

Check #82

Apparently, they are not going to add this feature.

@Code-ReaQtor - sort_keys was added (#161). I imagine it is only a matter of time. 😄

[roniemartinez]

@klahnakoski yes! But the developers, at the time (3 years ago), are not into implementing the feature. Only them can tell if the decision have changed. 😄

[EhsanKia]

They said pull request is welcome, which means they are not working on it but anyone is welcomed to add it.

I have implemented this locally, but it's using code from #518, so I'm waiting for that to get finalised and merged first.
