Think about `range_long_to_quantile()`

[nikosbosse]

The function range_long_to_quantile() was previously used in score_quantile(). It transforms forecasts from a long interval format to a quantile format.

Depending on whether we want to support the interval format in the future (see #443), the function should either

• be deleted
• be renamed, e.g. to something like interval_long_to_quantile (following the naming of the function quantile_to_interval()

If we aren't using this we should remove it for now I think?

[nikosbosse]

Good catch. I moved this to the current release.
