Hi.
We have a problem.

we're serializing an IntRange from a server we want to upgrade to 1.7.20.  This ads the field `end_exclusive`.  We have clients which are not able to update kotlin as easily (apps in the wild).  They now get the following error:

```Unrecognized field "end_exclusive" (class kotlin.ranges.IntRange), not marked as ignorable (2 known properties: "start", "end"```
Does anybody know of a nice work-around for this.  we thought about implementing our own small dataclass on the serverside which adhers to the `IntRange` api of kotlin &lt;= 1.7.10, but it's seems kinda hacky...

Sounds like you’ve run into <https://github.com/FasterXML/jackson-module-kotlin/issues/582>, the fix will be in 2.14 and backported to 2.13.5

yes - thank you very much!
