Fixed data was truncated on a property value longer than 255 chars

[andy1xx8]

Hi.
If the data is longer than 255 characters (hardcoded in the source code), it will be truncated.
This is a really serious problem because the URL from Google Ads is longer than 255 and was mentioned here #405

Therefore, this pull request will allow you to specify this limitation via config while constructing the mix panel tracking lib.

Have you tried running this locally for yourself? AFAIK there is still a server-side 255-char limit on string properties, so if you're trying to grab values out of a long URL with custom properties, you may need to do this on the client side and parse important params out of the URL yourself before sending (the way this SDK does for common UTM params and IDs).

Hi, I can't parse the URL, get the params and cut it off for 255 characters cause:

• want to keep the original URL as it is
• There is no way to form up the original URL if it was truncated
• I ( maybe many others) am using this client library and building a custom server-side API => So a custom server-side can handle this. Moreover, I think this client tracking lib should have the ability to change the maximum character length flexible
