Maximum length of AppVersion and OSVersion

[jakub-lat]

Hi,

While integrating Aptabase into my Unity game, I encountered this error multiple times:

Failed to perform web request due to 400 and response body HTTP/1.1 400 Bad Request

After investigating the issue with mitmproxy, I found out that AppVersion has a maximum length of 20 and OSVersion - 30.

The AppVersion length restriction is not so bad, because I can always trim it on the client-side. But as for OSVersion on Linux, the Aptabase Unity SDK automatically sets it to something like Linux 6.1 Debian GNU/Linux 12 64bit, which is a bit too long - and there is no way to change it, except maybe forking the SDK and trimming it manually.

Could you increase max lengths of those to for example 50, or add a setting to adjust that per-project? It's really annoying. I can submit a PR if it's not an issue to increase those restrictions.
